2x TESLA E88CC (= 6922, CCa, ~E188CC) Gold Pins, 32 Yellow Prints, 1970/71 Codes, 100%+ (364+368) You are bidding on 2 pieces of original 1970/71 TESLA E88CC/6922 tubes. These are TESLA Vrchlabi (= A.G.Lorenz before nationalization) production tubes featuring 32 factory codes, yellow logos, grey shields between systems, and gold-plated pins. These are very high quality tubes! These have 8/1970 + 9/1971 date codes, same construction. One has a yellow stamp between the pins indicating some kind of selection. Both tubes are in very nice optical condition (with only some marks on the pins indicating previous handling/testing or use) and excellent electrical condition, tested as 100%+ (and matched within approx. 15%), with following results: Tube 1 (364): Ia1= 16.90 mA / Ia2 = 15.70 mA, S/gm1= 11.40 mA/V / S/gm2= 09.80 mA/V Tube 2 (368): Ia1= 15.60 mA / Ia2 = 12.90 mA, S/gm1= 09.80 mA/V / S/gm2= 09.70 mA/V ...where a new/unused tube should have S/gm around 7.50 mA/V, and emission approx. 11-12 mA. Paired from a large lot of NOS/spare tubes. I have more vintage E88CC, ECC82, ECC83, and ECC81 tubes for sale in my other listings.
