2x RFT 6SN7 (ECC32 5692 VT231), Ceramics Spacers, 1953/1954 Codes, 100, Rare
Item History & Price
2x RFT 6SN7 (ECC32 ~5692 VT231), Ceramics Spacers, 1953/1954 Codes, 100%, Rare!
Reluctantly selling two RFT 6SN7 tubes in excellent condition. These come from military stock. 1953/1954 date codes and military markings on the glass! One tube is NOS/mint (and features newer RFT print; construction is the same), the other has slightly smeared print, and some shading inside the glass but tests excellent. These have beautiful construction with ceramic spacers, wire holders, dual fo...il cup getters, and smooth welded plates, reminding me of the special-quality Bendix tubes. These were not economical to manufacture, and only a handful of these were made, making them very rare nowadays. The tubes test 100%, and are matched within approx. 10%:
Tube 1: Ia1 = 13.70 mA / Ia2 = 12.80 mA, S/gm1 = 3.30 mA/V / S/gm2 = 3.10 mA/V
Tube 2: Ia1 = 11.90 mA / Ia2 = 12.90 mA, S/gm1 = 3.00 mA/V / S/gm2 = 3.40 mA/V
...where a new/unused tube should have a S/gm = ~2.20 mA/V! I will guarantee the tubes to test 90-100% on your tester and sound good in your amp. Returns accepted for any reason provided they are returned in the same condition. Also tested for leaks and shorts under both hot and cold conditions.
I have more vintage 6Sxx tubes for sale in my other listings.
See my other items for more vintage, rare tubes: TESLA ECC803S, E88CC pairs, NOS NIB 1950s foil getter Tungsram EZ80 singles/pairs and more... I have too much spare parts in my collection, time for a storage cleaning, don't miss out!Payment:
- PayPal (Preferred)
- Cash on Pickup
- No other method of payment (checks etc.) accepted.
- The shipping listed is for a 'registered airmail' method, which is fast, but does not provide insurance. I can arrange for any other shipping method available (UPS etc.), but you are responsible for all the (usually higher) fees. Whenever possible I will combine multiple auction items one eBayer wins to save on shipping.
Terms: This is a private auction and the item described is sold "as is", without warranty. All the items are sold from my private collection. Winning bidder must contact me within 2 days after the end of this auction. I expect to receive payment in maximum of 7 days after the end of auction, otherwise I will have to report the non-paying bidder to eBay and ask them for a refund. I am responsible for eBay fees, buyer is responsible for all the fees associated w/shipping, money transfer or customs in the country of destination. I can accept Escrow.com (only for valuable items, of course), but buyer must pay for all the associated fees.
