I put the scope on pin 8 of the 6sn7 and read something but i had to crank the scope WAY down to 10m volts and 10ms time. Read the same on the probe. Volts on tube plates are hit and miss.
6c4 = -.6vdc
6sn7 v2 = 243vdc
6sn7 v3 = 195vdc
6sj7 = 260vdc
6sg7 = 11vdc
Why does the pic of the 6sn7s look different?
Whats next to check?
