Hi Andy,
Thanks for the updated service data. Actually, it's not all that different in overall topology, which isn't all that surprising. Audio amps tend to follow a common theme... As a result, I think that most or perhaps all of my previous questions are still relevant.
Nothing wrong with being a beginner! Everyone has a different approach anyway. I tend to be a bit "theoretical", and like to know how the circuit should be functioning before doing anything else - that approach is admittedly slower than someone else who might jump in and so the "common sense" stuff like swapping caps and sweeping for dry joints, but my approach does have a higher success rate, and is more intellectually satisfying. But it might not put bread on the table - in the trade, time is money!
Also, I like to take the time to see how it works because I can learn new techniques or tricks that help me become a better designer. I think of myself as a designer first, repairer second, but in practice, that balance changes all the time. Before kids, I had much more spare time to design stuff - sometimes simple, sometimes quite complex - but now, I find myself doing more repairs because that fits in easier around family life and work (and it pays a little bit too) - the design stuff tends to be simpler, more self-contained projects that fit a need rather than being driven by interest or research. As the kids get older, the balance will no-doubt shift again...
Anyway, I see this amp has loudspeaker switching, unlike the 1070 IIRC. Stating the obvious, I know, but it might be as daft as switchcleaner
Cheers,
Mark
