Nick check for vent blocks and amount of heat from power transformer (which could be failing) 1.Check the electrolytic capacitors in and around power supply. 2.Check shunt, fusable and other resistors in the same place...3 Check outputs from voltage regulators, 4. Check rectifier diodes. You need an ESR low ohms meter to check caps and a multimeter for everything else. Go for it. Peter Lowrie |
