When I got my Sov2 I had similar probs with distortion and instability, distortion was caused by breaks in a couple of Pcb tracks near the pads and instability in AM by the main decoupling cap.
Once I had a Sony KV1300 tv, which used to blow around 20 transistors when the PSU packed up, £60 per hit, after the second time I built a new Analogue PSU.
I've often wondered what the real prob was, Sony reckoned a noisy thermistor.....
Back to the Hacker, I would have kept the original board and sorted it later or sent it to Mark !!!!!!!!
