2x TESLA ECC803S (CV4004 7025), 1966/1967 Codes, Matched/Balanced, Worse Prints = Discount, 100%+, 96+99 You are bidding on a matched pair of original 1966/67 TESLA ECC803S / 12AX7WA tubes. These are rare tubes made by TESLA, with large O getter, long ribbed plates, non-corrosive pins, controlled heater warm-up technology, and yellow prints (these feature the later 32-style logos). These are industrial-grade tubes designed for long life and rough operating conditions. These have 2/1966 + 6/1967 date codes, same construction. Both tubes have partially smeared prints, and are priced accordingly. Both are tested as 100%+, matched with balanced sections (within approx. 10%): Tube 1 (96): Ia1= 2.30 mA / Ia2 = 2.60 mA, S/gm1= 1.90 mA/V / S/gm2= 2.00 mA/V Tube 2 (99): Ia1= 2.40 mA / Ia2 = 2.60 mA, S/gm1= 2.00 mA/V / S/gm2= 2.00 mA/V ..where new/unused tube should have S/gm = ~1.60 mA/V, good starts at 1.2 mA/V. These are great for hi-fi, as well as for all guitar amps (Marshall, Fender, Orange, Selmer, Vox, Laney etc.). The TESLAs ECC803S are on par with Siemens E83CC, Telefunken ECC83 and other great vintage tubes, some like these even better. Do yourself a favor, and re-tube with vintage tubes. I have more vintage ECC82, ECC83, and ECC81 tubes for sale in my other listings. See my other items for more vintage, rare tubes: pairs of AZ11/AZ1/RGN1064 mesh plate rectifiers, NOS TESLA E88CC and ECC802S, ECC803S triodes, NOS NIB 1950s foil getter Tungsram EZ80 singles/pairs, and more...

2x TESLA ECC83 (=12AX7 B339 6L13 CV492), Foil Getter, 1961 Codes, 100%++ (48+51) For your consideration, 2 pieces of *original* 1961 TESLA ECC83 tubes. These are the rare first production ECC83 variant TESLA made for a short time during late 1950s and early 1960s. They feature foil disc getter on a large and robust support, smooth folded plates, non-corrosive pins, and yellow prints. Newer variant of the logo. Print on both tubes is very nice, these are near-mint/NOS! Some isolation paint loose inside, which is normal for these, isolation tested and found to be excellent. These have 1/1961 + 9/1961 date codes, same construction. They test as 100%++, and reasobably well matched/balanced (within approx. 10%), with following results: Tube 1 (48): Ia1 = 3.20 mA / Ia2 = 3.20 mA, S/gm1= 2.20 mA/V / S/gm2= 2.30 mA/V Tube 2 (51): Ia1 = 3.50 mA / Ia2 = 3.40 mA, S/gm1= 2.40 mA/V / S/gm2= 2.30 mA/V ...where a new/unused tube should have S/gm = ~1.60 mA/V, good value for transconductance starts at 1.2 mA/V. Paired from a larger lot of NOS tubes. These are NOT re-branded RFT tubes, but genuine early production TESLAs. Very rare tubes nowadays, because soon after introducing these to the market in the 1950s/1960s, TESLA stopped production of ECC83 tubes, and made only ECC803S and E83CC variants, while re-branding ECC83 tubes from RFT (from approx. 1963 onwards).I have more vintage ECC82, ECC83, E88CC, and ECC81 tubes for sale in my other listings. See my other items for more vintage, rare tubes: pairs of AZ11/AZ1/RGN1064 mesh plate rectifiers, NOS TESLA E88CC and ECC802S, ECC803S triodes, NOS NIB 1950s foil getter Tungsram EZ80 singles/pairs, and more...
