problems with my amp...

[Paul P]

i definitely pin pointed my problem, V3 is the culprit, i hope i mesured the pins again and heres what i got:

1: 225v
2: 107v
3: 107v
4/5 and 8: 7v
6: 0, it should be 110 tho right?
7: 0

i measured all pins to ground except 4/5 to 8. is it a bad tube?

Your 7v should be betweeen 4/5 and pin 9, not 8. These are the pins for
the heaters. Where's your pin 9 in all this ?

Yes pin 6 should be 110v according to the schematic but in my experience
(not much) that's a pretty low voltage for the plate of a ECC83(12ax7)
and might not sound very good.

i was writing the info down incorrect it was 4/5 and 9, sorry. i got channel two working by replacing all some of the resistors. it only works halfway now tho it only works withe gain boost on ++.

it actually sounds great, very AC/DC crunch, but i need to get + working.
