When capacitors C140 and C141 (figure 2 below) were replaced the voltage in the purple line dropped to 9V.The negative producing capacitor was questionable because a few people suggest bad negative power supply.

All transistors were tested with a logic probe and compared to new transistors. They function in identical fashion to new transistors. This probably indicates no problems with transistors. Resistors in the purple line and some beyond were removed and check outside. They all checked fine.

What is my next suspect? I’d be happy for any practical or unpractical suggestions. I wish I had variacs, tracers and logic probes. I will save up for them.
