I was still having problems with the voltages that I thought I fixed. I think I finally solved the issue, let me know if this is right.
I plugged the Eros into my system. Prior to putting in the tubes all of the resistances were correct. All of the tubes and the LED's light, however on measuring the DC voltages the B side Kreg measures 0 V DC and on the A side registers correctly at 1 V DC. Tracing it to the B3 and B8 pins measure 0 V DC, the A3 and A8 voltages measure 1 V DC
Unplugging and checking the resistances with the tubes in, the B3 and B8 the resistances would climb starting at about 27-28 and on the A3 and A8 would start around .3 and climb.
After plugging it in even though I had to turn the gain up one channel seemed very muted and distorted.
Unplugged it and started to check numbers again.
I would always get higher climbing resistances on the B3 and B8 when I left the tubes in and unplugged to check.
On checking voltages with tubes in on the B board I would always get 0 v DC for the Kreg where it should have registered 1 V DC.
Unplugged and checked all of the wiring from the power supply. I resoldered all of the connections which led up to the Kreg including B3, B8 the terminal strips, jumper wires.
I then retested and kept getting the same numbers.
I then switched the tubes around putting A into B and B into A. When I did this now the B board registered the correct Kreg of 1 V DC and the A board now went to 0 V DC.
So I think the problem is with a bad EF 86EH tube, is this right or am I still missing something?
Is there a way to just check the tubes to see if they are working well?
