Hello!
My Musicman HD150 head suddently lost most of its power/volume.
Its has a solid state pre and a quad 6L6 power section
I have previousy changed all the electrolytic caps and fixed several old solder points, but this time i cannot find any obvious problems.
All the tubes light up, and with the same intensity
The amps still sounds "ok", and both channels and both outputs behaves the same.
Here are the schematics...

Can anyone help? Where should i start? OT or preamp transistors?
Best Regards,
Lars Tore
