Ok, will shoot some detailed pics of the solder site.
Send/Return were cleaned (only return has shorting jack), but not resoldered.
Low voltage power supply was checked and partially rebuild (new 100uF caps, paired 15V zeners, approx +/- 16.2 V on both rails).

i'm stopping for a scotch break....
Thank you and enjoy your scotch.
just be careful...as someone who does a lot of repair work blanket solutions means that you never learn the details of the fault and that would make me lose sleep and drink more scotch...
considering some jumpers have been employed in previous repairs is it possible the board was flexed enough to develop a crack (try backlighting it see if you notice any cracks in the phenolic)
and a magnifying glass does help in exposing faulty solders.
