Hi J M,
Thanks for your inputs -- I like the series light bulb idea.
If I understand all that you suggested:
-- I'll remove TR3,4,5 and 6
-- Replace TR3 and TR6 with new parts leaving TR4 and 5 off board
-- Hookup the series light with the amp plugged into it
-- plug the light fixture into AC outlet and turn on the Amp
-- If the light is dimly lit, then all is OK up to the input of the MOSFETS
-- If this is the case the problem is either the MOSFETS and/or TR4 and TR5
At that point if I replace TR4 and 5 with new parts (power off), then repower with the light fixture hooked up and the bulb is dimly lit, the problem is fixed. If the light bulg glows than the problem is with the MOSFETS.
Is that about right?
PS. I'm heading out for the weekend now and will be back on Sunday -- Thanks again for your help.
Regards,
Jack
