| Transistor Devices Inc. DAL50-15-100  CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
50V/15Amp, 100W Transistorized Active Load by Transistor Devices Inc. Compact bench unit allows both resistive and constant current load simulation with full scale current from 1.8 to 16A on the meter, works from 3 to 50VDC. Also has a crash short-circuit mode to test power supply response to short circuits. Very simple to use, select the range, and mode, and start at minimum current, then turn the front breaker ON, and dial in the needed current. Great for power supply testing, we use these here for load testing, TDI units are available up to 1000W in bench units. Has front handles and feet. Does not require a fan, convection cooled. Fresh cal on each unit. Factory Manual is HERE. Last 1, $149 Ea. CLICK HERE to E-Mail us an order! |
Custom Load Box CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
Custom Made Transistorized Active Load Compact bench unit allows both resistive and constant current load simulation with full scale current to 30A on the meter, works from 3 to 32VDC. Made with some kind of potted load module, and fan cooled, looks to be good for about 100-150W max. I have run it up to 32V, but never used it above 10A, and I have no data for it. It works well, needs at least 3V to operate. A nice unit for the price, even if it is a bit mysterious in origin, and ugly at the rear. I put new knobs on it, and the meter is accurate, so comes with a cal. How can you go wrong with this unit? The Phaostron 30A meter is worth it alone. Great for power supply and battery testing.

 Tek 1502 With Lid, Battery and Printer!Tektronix 1502 Time Domain Reflectometer Very nice looking Tek 1502 with bright CRT, detachable high contrast light shield and front cover. Has working battery pack, plus a 1503 field op guide and reference BNC 50 ohm load in the storage lid. Works well, the pics show I used a 3 1/2 foot test BNC cable with and without the Tek termination, and got accurate results, and printed them to the printer. Even the tiny disturbance of the BNC connectors at the load is visible. Might require a cal, as I did not have a way to do an exhaustive test of all ranges, but it is certainly functional and useful. I had three, and kept the best one for our lab (this one), but wound up just never using it, so it's time to move it on to somebody that does lots of field and cable work. Some case marks and label residue I couldn't get off, but over-all very good physical condition. BE AWARE, a charged cable or applied voltage can destroy the internal TD pulser, so ALWAYS DISCHARGE AND DISCONNECT ANY CABLE BEFORE TESTING and that is your responsibility. The OP Manual is HERE.

Tektronix Late 515A 15MHz Scope CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
 CLICK for Bigger PIC! Tektronix Late 515A 15MHz Scope Beautiful condition inside and out with excellent appearance, the red variable knobs still have that rich red color like when new. CRT is bright and crisp focus, has green contrast filter and red graticule, the fan is smooth and low noise. Has the final silicon rectifier power supply and late transformer. Single trace with dual switched inputs foir convenience. Note the clean interior of the unit and good covers. This later A-version has BNC inputs and 50mV sensitivity. Works great, I cleaned every rotary switch by hand with de-oxit and a q-tip, and operation is solid, all controls and switches work properly, and it comes with a CURRENT CAL. While spec'd to 15MHz, it was usable to 25, but the triggering is tricky even at 10MHz, and requires use of the stability control as well as threshold for fast waveforms. A great example of classic tube design from Tek. The manual is too large to put here, but will be included on a CD. Has the old style power connector, I am including an adaptor and IEC cord for it so it is ready to go. I am amazed at the over-all condition of this older tube scope scope, it looks very fresh and unused, serial number is 009239, towards the end of production in the late 60's.

Tektronix P6042 50MHz Current Probe CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
Tektronix P6042 50MHz Current Probe This is an amazing bit of engineering, combining both an AC current loop and DC hall effect sensor to give DC-50MHz bandwidth in every measurement. This design later became the AM503 current amplifier. The probe is in excellent condition, and works great, including the latching mechanism. Only issue is that the cord is a bit stiff. I cleaned the range switch and changed the main filter caps due to age before starting to cal this, and got everything working down to about the 20mA/div range. at that point, the DC offset throws the trace off screen, the DC step balance is not correctly adjusted yet, might need a few more caps changed, including the degaussing charge cap. Works for both DC and AC currents, and general operation is good,, except as noted, so as-is. The manual is HERE. Just 1 unit, $195 CLICK HERE to E-Mail us an order!$195 |

ARGO Systems AS-210 Modules to make Custom TM500 accessories!. To answer the request for a way to make custom TM500 items, here are some more clean AS210 modules, made with genuine Tek hardware, so they are an exact fit into TM500 frames, and look identical, BUT if you try and use the card edge, be aware it has NO slots cut in it and different pin assignments! Slots are required for use in a TM500 frame, and the edge fingers have to be cut away from tracks with a Dremel tool if you are going to try and re-use the PCB. These have faults, so for salvage only (every IC is socketed!), and DO NOT plug them into a working TM500 frame as-is, as they will kill it. They are complete with pull tabs and side covers, no broken corners, all in great shape. AS210-01A controls have keyboards and displays, $29 each, we have 2 units. The AS210-04 controls are single wide, with thumbwheel switches and loaded with circuitry, $39 each, have 2 units. I have a giant manual file with info for this system HERE in case it is useful.

CLICK for bigger PIC! |
Tektronix 119-0503-00 TCXO 5MHz Oscillators These require at least 21VDC to run (probably for +24VDC supply), and output a TTL compatible waveform at around 2.5V. They only draw roughly 30mA, and don't get warm, so can't be OCXOs. Both have the same footprint, work great, fully marked on the back for connections, used in some TM500 counters and possibly elsewhere. Nice time base for something.

Assorted RF Wattmeters, RF Amp + Dummy Load CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
Assorted RF Wattmeters, RF Amp + Dummy Load This is a good assortment of useful Broadband RF wattmeters (30-600Mhz) and related items, all of which need attention. The ME-11C/U unit has a built-in 50 ohm load, but reads low on both ranges (load is fine, even though rear N connector is slightly bent), may be the detector diode or just adjustment. The factory manual for it is HERE. The Bendix 711N4 through line unit has rust on the internal pots, and is intermittent, so it has to be opened, cleaned and re-cal'd. The two 1N21B detector diodes are good, The ENI 500L RF Amp outputs full power only at low frequencies, needs repair. Lots of handy RF lab bits for just $75.

Assorted Digital Meters CLICK for bigger PIC! |
Assorted Digital Meters These are good looking meters, but need some attention. The thermometer always reads 16.6C with the probe connected, the Exetech has an intermittent connection at the upper top left of the display, should be an easy fix. The three red DMMs are un-tested and need batteries. These are all that's left of a big pile of DMMs we bought from a distributor to make cheap student meters, most were good or with very minor faults. We're just tired of doing them, so it's your turn.

AVO MK.4 Valve (Tube) Tester CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
 CLICK for bigger PIC! AVO MK.4 Valve (Tube) Tester I spent an absurd amount of money to get this tube tester, to have coverage for many Euro tubes I could not do with my other sets. It is very highly regarded, and well documented, so I thought it was worth the price. When I got it, the meter was dead, which was quite a disappointment, more so because the internal design of the meter is very odd, and despite efforts from some adept friends, we just could not get it working. Being a 30uADC meter, spares are hard to come by (I chased on all over the planet looking), and it took me a year to find the 25uA meter shown on top of the unit, I figured I could make that work effectively with a bit of shunt resistance. However, I just had too much to do, and this sat for another year, so now it's stuff season, and it's headed to somebody else that needs a high end tube tester, and isn't afraid of a bit of work to get there. Restoration notes are HERE. The service manual is HERE, the operators manual is HERE. Tube data is HERE.

Efratom MDP 1pps Modules, 104701-005 These distribution plug-ins all came from two 1pps (one pulse per second) timing shelves, and all had the same fault, they output a strange half-amplitude runt pulse, without the master 1pps input, shaped like a narrow letter M, while faintly pulsing the FAULT LED at the same time. There is no obvious internal fault, power input is good, and the fuse is intact, but all of these have the same fault, so provided here for parts, repair or the enclosures. Good units work correctly in the shelf, so the fault is with these modules. Have 6 Left, $5 each |

JFW 50FH-030-100-2 100W/30dB/2GHz Attenuators JFW 50FH-030-100-2, 100W/30dB/2GHz Attenuators, one of the most useful items on an RF test bench, the 30dB power attenuator allows transmitters (to 100W) to be measured with a regular 50 ohm power meter, converting Watts to Milliwatts, and simultaneously providing the transmitter load. These used units have been fully sweep tested, and are flat to 2.4Ghz, and accurate. They are natively N(M) to N(f), but since the N(m) end is often awkward to connect on the bench, we have added new high quality Amphenol barrel connectors, to make both ends female, for ease of cabling and power sensor connection. Heavy, the bulk of the unit is heatsinking. We can add rubber feet to the bottom if you wish. Catalog data is HERE. LAST ONE!, $125 Ea. CLICK HERE to E-Mail an Order

Regular and HD D-sub Connectors Mostly new top quality D-sub connectors, from 9 to 104 pins, approx. 90 pieces. A few ribbon cable crimp types, mostly solder and PCB mounting versions. Lots of gold contacts here, and some pricey HD high-density parts, a great lab assortment for developing and experimenting. These were from an R+D bench, stashed in some forgotten drawers. For clarity, Cannon developed these many years ago, and all numbers begin D, followed by the shell size letter, A-E. Thus, only 25 pin versions (shell size B) are actually DB connectors, all other have a different prefix, DA (15), DC (37) DD (50) and DE (9). Just a bit of useful connector history.

Copal 10-Turn 10K pot + Digital Dial CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
Copal 10-Turn 10K pot + Spectrol Digital Dial 10-Turn pots have many uses, but generally they do not have high absolute precision in their total value, so a 10K pot might be +/- anywhere from 5% to 10% even in high quality pots. These Copal parts not only have 0.2% linearity accuracy, but all measure better than 9.95K, or better than 0.5% tolerance. This makes it possible to take a turns-counting dial and the pot, and have it read out directly in ohms (9.50K, dial reads 950, a decimal can be easily added) for use as a high performance resistance substitution box. We have 4 pots and 4 dials to make up these useful design standards. They can also serve at a calibrated voltage divider. We will ship the closest tolerance parts FIRST.

Triplett Model 60-NA VOM CLICK for bigger PIC! |
Triplett Model 60-NA VOM Sometimes a mechanical meter is more suitable than a digital one, especially if you are using military manuals, which specify a VOM, not a DMM, and have different values accordingly. This is a nice later, ruggedized case meter from Triplett, uses the reverse banana connections, so I am including two new sets of leads for it, as they are not common. Cal is current, and fresh batteries, except the 30V one for the high ohms range, BUT it is still very good, and works fine. 20K/10K ohms/volt on DC (has a half range switch), and 10K/5K ohms/volt on AC.

$5 COMPACTRON Tubes CLICK for bigger PIC!  CLICK for bigger PIC!  CLICK for bigger PIC! |
GE/RCA/Sylvania COMPACTRON Tubes Compactrons were developed at GE in 1960 as a response to the new transistor developments. In essence, they were the tube equivalents of ICs, with as many elements as possible, requiring reduced power, jammed into one glass tube. The original concept Compactrons all used the Duodecar 12 pin (3/4 inch pin circle) base, and had the glass sealing tube at the BOTTOM, unlike most other tubes. The beauty of these designs is that often complete functional blocks or even devices could be implemented with one tube, or one and some external support like power rectification or an output stage. Their charm for audio experimenters today is that same compact format, which makes minimal tube count equipment possible. This group of tubes is priced at $5 a tube. Matching PCB sockets are available for $2 each (available ONLY with tube purchase). The internet is full of COMPACTRON based audio circuits, so Google away.

HP 606A HF Signal Generator CLICK for bigger PIC!  CLICK for bigger PIC! |
HP 606A HF Signal Generator This was a total basket case when I got it, missing the main tuning knob, broken attenuator, corroded connector hardware and dead as a doornail. Plus, it looked bad. Not a happy bit of gear, but I felt it had promise, and I have always liked these units. I tore it apart and fixed all the broken, misaligned and tarnished band-switch stuff, got a new attenuator assembly and replaced it, along with the power switch, phones jack and BNC output jack (really not a trivial task, by the way), and a pile of capacitors and 12B4 tubes. Found the output meter was bad, and had to go hunt another good one down. Finally after three months, I got it all running, and re-painted the case matte black (looked way cooler in my mind than the already re-painted and beat-up gray). The range of this unit is 50KHz to 65Mhz, and has both internal and external AM modulation (up tp 20KHz), perfect for anyone doing SW receiver work. Alignment and operation are good, only one issue remains, I cannot get the +20dB position to work, something is amiss with the replacement attenuator outside rear wafer switch or my wiring to it. It's going to stay that way, as we put more into it just in parts than we are asking for it. A wonderful classic HF generator, now in great shape, and includes the original factory manual. Pick-up is best for this, as it's very big and heavy, and the huge rotating band-switch assembly does not travel well by post. Just 1, $225. CLICK HERE to E-Mail us an order!$225 |

ITT Schadow Lighted NE-18 Power Switch |
These beautiful lighted DPST 8A rated AC Power Switches make any project look good. The lamp is a neon (glows orange, not sure why the lens is green) with no series resistor, so add minimum 33K 1/4W at 120VAC. The NE-18 industry standard power switch is robust enough for almost all applications. Mounting Hole Diameter is approx. 0.53" so it can sub for the impossible to find HP white button lighted power switch, and will work the same (hole may have to be slightly reamed out to fit.

  NEW Powerful DC gearmotor custom made for Diebold by Igarashi Motor Sales USA, based on the N2732 27mm motor core and a 33mm diameter gearhead (33GN2732 series). Amazingly powerful for such a small motor, the gear ratio provides very high torque. Exact data is not known, but measurements show it seems to a ~9VDC motor at 0.13A (no load, ~100RPM) and runs down below 5VDC (5VDC at 0.08A (no load, ~50RPM), and up to 12VDC at 0.28A (no load) with no difficulty. Fully loaded mechanically, the current is roughly double. The drive shaft is a flatted 5mm steel shaft. See full dimensions HERE. They are excellent for all kinds of electromechanical devices, with enough rest friction to allow the motor to act as a brake on the drive shaft. Tapped holes (3 x 3mm) on the gearhead face ends of the motor for attachment. Fully reversible, with all leads floating, it has a 2mm mating connector, and the Tyco pc mounting 2mm connector is INCLUDED. Like all brush DC motors, some L/C filtering is useful to prevent interference with other parts of the circuit. New and unused, ready for your application!

Weston/Schlumberger Model 640-60 Foot-Candle Meter Very nicely made Weston light meter (calibrated in foot-candles) with a tilt-up sensor (filtered) and 3 ranges. The range switch is not intuitive, there is a dead position between each setting, so it can make you think it is not working, and rotates too far. However, it works on all three ranges. The detector is photo-voltaic, as no batteries are needed, and the green filter corrects for the detector red sensitivity. Has a nice solid black phenolic case with hinged cover to protect the instrument. No idea of the production date, possibly the 60's. Just 1, $49 CLICK HERE to E-Mail us an order!$49 |

Sylvania You can reserve these for pick up or order NOW for shipment by emailing walter at: walter2@sphere.bc.ca. All are clean, at least filament tested or known to work, some are factory new (NIB). This means you can pick them up or have them shipped, but first come, first served. Keep in mind, the cheapest shipping for a full sized CRT is about US$50 in North America, US$80 as insured trackable, so pick up makes real sense, as it might pay for your gas up here. |
