Hello all,
Thanks for the input. I may do the dishwasher suggestion as I plan to remove all the transformers anyway. I am not sure about removing the daughterboard but I may attempt because the electrolyte did flow through there. Its really a shame.
Results of diode and transistor testing (in circuit):
-The SCR on the daughterboard has
very low resistance between all three pins so I believe it is bad.
-All other diodes and transistors seem ok, some had low resistance between some transistor pins but this could be traced to a low value resistor between them.
I wonder would the SCR have taken out any other components?
Re the trimmers, does anyone have specs on the originals? The two in question, R40 and R58 I can not discern any writing on them. I have 1/2 watt multiturn on hand in many values
So moving forward I plan to:
1- Remove other transformers and continue to clean.
2- Possibly remove inductors
3- Possibly remove daughterboard and clean
4- Replace bad SCR
5- Replace R40 and R58 trimmers.
6- Install new caps
7- Reinstall transformers
8- Test
