Unhappy 6505+ combo lead channel not working

The "rhythm" channel (both clean and crunch) works fine, but the lead SOMETIMES (with both the post gain and pre gain turned ALL the way up) produces a quiet, clean tone, not a lead tone.

I've redone all the tubes What do

You replaced all the preamp tubes?

Past that point take it to a tech. Sometimes the solder joints crack on the 112's.

Could be a bunch of things. A good tech will fix it in no time.

How old is it? Could still be under warranty.

Post back with what they find. It will help others later.

Got it used, no idea :\ The seller says it has been working before.

Taking it to a tech is pretty hard. It's heavy, and I'd have to carry it :\

+1

It could be any number of things that have just went bad, happened to me recently.

Without a Scope and a good idea of what you are looking at, it is pretty hopeless trying to fix it yourself.

Do you know electronics? Comfortable with. 400v+ volts that could kill you twice over?

If not lift it and get it fixed.
