Hi all
I have one of these old British made Valve amps ER15 all original never been touched
Strange fault !!
when you plug into channel 1 and turn volume up, its ok but the bass control acts weird , you have to have it about 12oclock otherwise you get no volume from that channel, Does the same on channel 2
If you use channel 1 and turn the bass on channel 2 it effects the signal from channel 1 and visa verse
Treble working correctly and causing no issues
so it looks like there is some bleed through somewhere
I have checked and swapped the tubes, Cathode bypass caps all bad so all electrolytic been changed
i was given a second one which i have now repaired and that one is working correctly
Cleaned all pots , its not an intermittent pot type fault
never really encountered this type of fault before
this amp is all original and don't really want to change components on the off chance that it might fix this fault
