Hey,

This is an older 18 watt tremolo clone that has worked fine for three years.  One day it just started playing at very low volume.  Filter caps seem all fine as well as the tubes.  Some funny voltages on v2 and v3...

v2
1 - 85
2 - 17.5
3 - 22.2
6 - 85.1
7 - 17.6
8 - 22.2

v3
1 - 161.7
6 - 105

All the other voltages seem fine.  What would make the v2 voltages so low?  The 470k and 820 ohm resistors on v2 seem to have drifted a bit high (620k and 1k).  Other than this everything else looks good and the tube is good.

Any ideas?

Cheers!
