Hi everyone.
I have a pathfinder 15r with no reverb
I understand its a practice amp. But the owner
Really loves it. So please no bin it comments
On inspection I can see the tank is ok
128ohm input 228ohm output
I connected up the signal gen and I can see the signal on the input. Output signal is very weak. If I rattle the can just hear it through the speaker.
I connect up a speaker on the return and tapping the speaker can't hear anything
I feel sure it's a return issue?
I have decided to try a few odd tanks I have around. Still nothing.
Changed the op amp. And checked supply voltage ok
Hardly any signal getting to pin 6 of op amp with same on pin 7.{ic5} Checked and changed the reverb pot
Working well apart from this. Tremolo working
I've run out of ideas. What's going on. Am I barking up the wrong tree
