Matched Pair RCA 8FQ7 8CG7 6FQ7 6CG7 Vacuum Tubes Valves

Matched Pair RCA 8FQ7 8CG7 6FQ7 6CG7 Vacuum Tubes ValvesThis matched pair of RCA 8FQ7 dual triodes was tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured 67 in Section One and 65 in Section Two for Tube One and 67 69 in Tube Two where minimum (65%) is 50 50 and 100% is 77 77. They have gray plates; steel support rods; side, D getters and outstanding flashing. As I write, I am playing them in my Sound Craftsmen RC 2

side horshoe getters

45 and 46 where minimum (65%) is 29

Tube One Transconductance: 45/45

Unfortunately I can't tell you how they sound as we do not have any equipment that uses them nor do we have adapters at this time

excellent flashing and three horizontal holes underneath and parallel to the plates' short axes

bottom D getters and copper support rods

8 milliamps' plate current / 2170 micromhos

THAT LOSS RATE IS REFLECTED IN OUR PRICES

It measured 78/80 where minimum (65%) is 50/50 and 100% is 77/77

Transconductance measured 59 for both tubes where minimum (65%) is 40
