Hello, I have a problem with my Sony 700ES. Well, more than one.
1- Red power lamp stays ON and does not switch to green even after relays seem to engage (this thing is full of relays, not just for the output connections…)
2- attenuator seems to leak some signal on either channel at both ends of run. i.e.: all down some faint signal on the right channel isntead of zero, the opposite at max volume (tried the later with damping engaged and no signal input …)
3- the channels are altogether slightly unbalanced (R quieter and hollower, L fuller and louder) and possibly slightly distorting at times.
I downloaded several of the service manuals available online but they're not really usable (especially because all the voltage ratings on the schematics were originally in red ink and kind of disappeared in copied/scanned black and white images in pdf's.
Can anybody shed any light..?
Thanks

hello, you mean that’s the only section I should be focusing on..?
that might be a lucky bit but the rest is not very readable🙁

most of the fusible parts and pretty much all the ‘higher voltage’ sections that had, originally, a grey background, for instance
