***Eimac Electron Tube 7203/4CX250B Metal Tube 250W*** Normal 0 false false false EN-US X-NONE X-NONE Welcome. This listing is for an Eimac Electron Tube 7203/4CX250B Metal Tube. This is a N.O.S. item (New Old Stock). I‘ve a couple of these new and several more that are apparently used. I would like to hear from anyone with experience in testing these. I need the settings to test them on one of my tube testers. (I have several, but these are too recent for any of my charts). I also have a few sockets available for those interested. Thanks for looking and be sure to check out my current auctions for other interesting items. E-mails: I will do my best to answer any question sent to me regarding my auctions. Shipping is figured for the winning bidder ONLY! This include both domestic and foreign. Ive had as many as 14 requests for shipping estimates on a single auction! (And not one of them bid!) Payment & Terms: Paypal. Have another payment plan? e-mail me. If it doesnt involve a personal or business check, we can talk. Packaging fees are common sense based. Im just interested in covering the time & materials used (Usually $2.00-15.00). 99% of my auctions got out at the lower end of that list. The more time & materials used, the higher the fee. You wont find an $8.00 handling charge masquerading behind a 99¢ auction here. And if you think about it, youd really rather spend the money on careful packaging than to have your fragile purchase just shoved into some old box and sent to you unprotected. Ive had that happen and so have plenty of others, but none of them were my customers. Shipping is done via USPS Priority Mail or FedEx Ground. Large/Heavy items (over 10#) are shipped by FedEx ground and require a street address, NOT A P.O. BOX. If you dont have an address, borrow one!

Because I dont know the operating condition of your equipment, tubes are sold as is. I may have several of the tubes being auctioned, and may NOT use a photo of the actual tube. There may be some larger type tubes that I do not have the equipment to test for other than filament continuity (Ill put that in the listing).INTERNATIONAL BIDDERS: Because I can only test for technical things like transconductance, gas, shorts, etc., I cannot test for things you might think you dont like (tone, response, etc.).
