Pioneer SX-636 30V on left output

I tested them, any I couldn't detect any issue which is why I put them back in but I just wonder if there 's an issue while under voltage. Because it's the only thing I can think of that I swapped.

I pulled fuse 1 and 5 from the power supply to double check if the transformer was at fault. My filter caps aren't putting out hardly anything at this point. I could swap them out first I guess, since I have them.

I've learned so much since I first started, I wish I was back at the beginning knowing what I do now..

check ac volts before rectifier
 
OK, you may be right Bass.

The only clue I've got is that I may have switched the output transistors in the Amp, which would explain why my left channel now is measuring 1.8 Vdc and the right is -55 mV dc. The opposite of before.

My dim bulb tester is burning really bright now, I am gonna go over all the installed parts to make sure I didn't install something wrong.
 
Yeah, I accidentally installed one side of the transistors in the wrong order (531<-->371) and it didnt light up as much as when I put them in correctly.

Is this worth ordering $20 of replacement transistors ?

been the past few hours making...slow progress with the 636 but i ran into a bit of an issue......the new trimmers do not fit into the holes of the original. since i got my new camera i can take good photos now.

the blue ones are new, brown is original and the diode is a 1N4004

what is stopping them from fitting ?

It's to small, the leads are too close together and there to short to bend them like i did with the transistors.
EDIT: looks like the bottom 2 leads fit while the top one is to close together. it MIGHT be able to bend to fit...
