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.
PROTOTYPE SERIE!

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= 4.00 mA / Ia2 = 4.00 mA, S/gm1= 1.20 mA/V / S/gm2= 1.20 mA/V
Tube 2: Ia1=
4.20 mA / Ia2 = 4.30 mA, S/gm1= 1.30 mA/V / S/gm2= 1.30 mA/V
