Hello everyone.
I have got a H&K Trilogy Head, and there's and big noise on the clean channel.
V1 tube 12AX7 has a bad microphonicity; i substituted it with some new tubes without results, so i think that there are other problems...
It's too hard for me tracing the circuit without the schematic.
I need a schematic...Can you help me?
Thanking in advance, best regards.
