I am currently working on recapping my Sx-1050. Do you folks recommend that I recap say the protection board and then a power supply board and then fire it up on the dim bulb tester at the completion of each stage to ensure that the recap and transistor replacements are working correctly? Amplifier was working perfectly prior to me starting the work. So far I have completed the caps on the Reg-a power supply board and the protection board. Transistor replacement will happen tomorrow.
BTW is there any real need to change out the resistors or diodes as some have suggested if they have zero signs of heat damage? The flame resistant resistor covers are still nice and white and when I pulled a couple from the power supply board they measured in spec still. I suspect that the previous owner was gentle on his receiver and never abused or drove them hard. I can't speak for the zener diodes but they too seem to be working just fine.
