A couple of months back, you were kind enough to scan and e-mail me a
section of schematic for an old Technics SU-V8. It has now come back with
another problem which, needless to say, is not covered by that section of
schematic. If it's not too much trouble, I wonder if I might ask that you
could do me the input board that has all of the rear panel phono sockets and
input select circuitry on, but also some power supply regulators - for
instance Q453 - which appear to all be switched off ...

TIA
