Between heating with the gun, and chilling the components, it takes hardly any time to find which component is faulty. Could be a cap, transistor or IC component causing it. Adjustment isn't going to do any good, you need to track down the bad part.Thank you for your advice; I will try it out.About 5 minutes after I posted my original question, I received a response via email:Your filter capacitors are cooked. Any tv repairman can replace these.
It is almost certainly *not* the "filter capacitors" (which refers to the capacitors in the power supply). It is much more likely to be a coupling or bypass capacitor in the cathode or grid circuits, or a high-value resistor in those circuits. -michael NadaNet 3.0 for Apple II parallel computing!
