Grabbed this from the dump one day. There was a large d battery sized capacitor that wasn't soldered to the board. Fixed that, now it makes noise. But it's more of a "pop" than it should be as far as a guitar string sound. Nothing seems burst as far as caps. It is scratchy even before the pots are turned. The treble and bass pots do next to nothing when turned. And the tremolo works very infrequently. I'd like any ideas/advice as far as fixing up this old amp. I mean, it's an amp! Smile the reverb is springs in a box and actually sounds pretty cool. It looks battered but that doesn't bother me. I'll try to put pictures up.

This is how I fixed my last '70s Marantz preamp.

Did it fix it? Is it a usable amp now?

bear in mind that Heath amps were kits. So you're at the mercy of whoever assembled the kit. There's no guarantee the amp EVER worked properly, in other words, so there's a small chance you might be up against a full rebuild. Still, that might not be too difficult given how well-documented those kit form amps tend to be.

In my case, yes. These old amps usually have bad caps in them after 40'ish years.

Hmmm... is there a preference, or should I just replace the components with similar or exact ones? Or is there a benefit to upgrading?

If you need to replace germanium output transistors and you can't find any, drop me a line. I've done it successfully (more or less) with silicon, in a Standel amp. You have to make small changes. I have a drawing.
