Standard Alphabetic Prefix Part Number CRTs- Cathode Ray Tubes
   Skip the INTRO, Go RIGHT to the CATALOG! These are the cathode ray tubes (CRT's) we have on hand from National, Sylvania, SONY, AEG- Telefunken, Philips and other key makers. We have some new (NOS), some dynamically tested used tubes  , and untested pulls  available. All CRT's have been tested for a good filament, and have burn-free phosphors. We have many Tek and HP scope CRT's here, both new and removed from equipment that was in working condition, ideal for reviving your favorite scope. GOT CRTs to SELL? We are always interested in good quality tubes! A typical 5 inch CRT now costs $35-40 to ship by insured ExpressPost.  NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!
You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST. OR, Email your order to Susan HERE.
 SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating. E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.
CONDITION: These are all inspected and where possible, fully dynamically tested. We offer only the best condition CRTs we can, any marginal tubes are scrapped. Note that CRTs are very fragile, and we have to pack them well to survive shipping, WHICH IS COSTLY. Please be aware that there is no such a thing as cheap shipping where CRTs are concerned.
