If you have any schematics that are at least similar, it would be
appreciated. Most of these amp manufacturers don't reinvent the wheel, and
the relay circuitry is quite likely to be similar between models


** Decades ago, I managed to extract some schems for C-Audio from the Aussie
importer ( same people who now make Rode Microphones). Not like normal
schems, these were large scale drawings with each part of an amp on a new
page - so very had to use in servicing. Chucked them a long while ago.

IIRC, the relay system was full of BF422 and BF423 transistors, all sitting
right in the fan blast, with badly corroded legs. Check and replace these if
needed and that may be all you have to do.

It was on one of these amps that I replaced BC182's with BC182L,s not
realising the pinout was different.
It was a week before I worked out what the f**k was going on there.
