Thanks guys.
I won't have a chance to look at it again until this week sometime. I'll check the speaker movement for DC and, as I'll have more time than the other day, I'll take it back apart and check for anything that looks loose, cracked etc.
One thing I forgot to mention the other day (and not sure if it's of vallue), but the buzz comes from either output. This amp has a direct out which delivers 300W into 2/4 Ohms and a X-Over out that delivers 200W into 2/4 Ohms. I might have those figures backwards, but the point is, it's a separate output channel since it runs through a x-over transformer, right? Anyway, as I said, not sure that adds anything.
The smoke, btw, wasn't some huge wildfire. it was more a single source point, like a cigarette inside the case, so I'm guessing that was a component burning. And it may well have been 20 years of dust on a hot point.
I'll report back later in the week after a better exam and the DC test.
Thanks again
Nick
