2x TESLA ECC802S / 12AU7WA
You are bidding on 2 pieces (matched pair!) of *original* TESLA ECC802S tubes.
They feature non-corrosive pins, old-style yellow prints, large ribbed plates, copper system and grid posts and large halo getters.
These are industrial-grade tubes made for army or aerospace use, and other demanding applications. Construction-wise, they are similar to the exceedingly expensive Telefunken ECC802S tubes, and some like these even better.
100% guarantee original Tesla, NOT JJ, not re-branded RFT.
Tube 1: Ia1= 3.40 mA / Ia2 = 3.20 mA, S/gm1= 1.10 mA/V / S/gm2= 1.05 mA/V
Tube 2: Ia1= 3.40 mA / Ia2 = 3.10 mA, S/gm1= 1.10 mA/V / S/gm2= 1.00 mA/V
Same datecodes: EJ = 6/1965
Extremely high quality audio tubes for hifi/high-end/guitar amplifiers.
