Nope, I haven't touched it. Two kids, a 50 hour per week job, and a fiancee that likes attention take up most of my time. She's headed back to Georgia to visit her family next weekend. I'll have to carve out a few hours to back those outputs out while she's gone. I was just planning on doing the filter caps and DC protect, but this issue has me strongly considering a full WOPL conversion.

It’s interesting watching people go through this cycle with 40 year old equipment.

If you want any duration of trouble free operation from this amp, replacing both the marginally assembled point to point sometimes soldered components and original control board is mandatory.

Give the White Oak components a try and if you need assistance, I don’t live far away…
