OK. Better than nothing. Flood it with flux (as you would braid).
If you're going to do this, you need a proper desoldering pump. Don't buy the small short type. Buy one like the Edsyn DS017. I know you won't be able to buy that exact one but even others similar will be better than the small ones.

First test, no input signal, just a speaker connected, DEAD silent , 0 , no more “radioactive” buzzing , 0,13v dc on all channels. I l connect now a music source to test all channels.
You’re right, I’ll fix this right away , i remove the board with heatsink , just two screws to keep it pressed . I think now it make the rated power , it sounds very clear and 2x louder then before.
Also what is a good solder and flux to buy? I also need to make a coupe of RCA’s , this solder it’s 30/70 and on large surfaces it’s difficult to work with , it just don’t stick nicely.

You probably can't get what I'd recommend because it contains lead. You won't buy a full 1lb roll.
24-6040-0039 kester
Flux, not critical but on eBay, search for:
Kester 186 951 reflow flux needle bottle combo xbox
^^^ Those are 2 different fluxes with steel needle dispenser bottles.

It is like 0.11-0.13 speaker or no speaker connected . It has 15 mins of playing , it’s very cold, also with no music playing no noise at all , no matter what gain, nothing 🙂
Can i work with the amp till Monday when the solder will arrive? And thank you sir for all your time wasted with me.
When you get the proper solder and flux, the solder connections should like the ones on the two large transistor's terminals. Smooth, shiny (if you don't use lead free solder), uniform. Clean the flux with acetone and a toothbrush (90% rubbing alcohol and cotton swabs are options). I should have cleaned these joints before taking the photo but, for some reason, I didn't.
It's not generally a waste of time for me. Virtually every post makes me review information I have and edit it where necessary.

I use a toothbrush and isopropilic alcooli for cleaning, then i let a napkin to absorb , it is a pain if the *** if cotton gets into a solder and stuck there. I’ll put it now on car and have a listen.
I made a test with the solder at work , i filer a home with it. It looks decent? Kester in my country seems impossible to find and big suppliers have large rolls that cost …
Also I tough that if i replace the parts with good quality ones this amp will perform as it was born or better. Now i read that the dc offset could be some upc driver that drifted.. and good luck finding a good or new ones.
