I do not have any specific experience with this amp.
You are going to have to trace it out & find where the signal is failing.
First thing that I would try to ascertain is : it a preamp or a power amp problem.
Divide to conquer.
Here is a link to a site that has the schematic.

You could try the pencil test... Jam a pencil into your ear. That should hurt

Just Kidding. The way you wrote it sounded like it was a goal to hurt your ears (nothing wrong with that).

The convertable is a really good sounding amp IME. I've been surprised at how they sound on two occasions. But I don't know which "module" was in use. It's these modules that have me suspicious. A removable card has to have some oxide and questionable connections in an amp that age. Perhaps try removing the preamp card and clean the male and female contacts. If the amp has an effects loop you can try slaving the power amp to see if it's in proper working order. This could help isolate the problem.

Have you tried swapping in known good preamp tubes yet? That's the first thing that I would do.

First thing I would do is patch a cord from FX send to FX return.
