In the low range of the volume of my Technics SA-GX130D the sound is poor. I think the potentiometer should be changed, but where can I find such. Tnx for helping me out

Your best bet is to get a spray that is called deoxit gold for cleaning the volume control potentiometer. You have to disassemble the case to get to the internal portion and it could also be a bad solder connection on the board the control mounts to.
On some systems F61 is to do with the fan not working properly, sometimes blocked with dust. On others it's a power amplifier failure. Yours does sound like a power amp problem, but both should be checked.
Hook the speakers to the remote terminals on the back and switch the front speaker control to select the remote speakers. If you have audio, your main amp channel may have an issue....
hello there are 2 big capacitor behind the metal heatsink see if one has swelled up if so change them both then check the output chip to see if there are any dry joints then when you've check all and still the same then you may have to change the output transistor g ood luck
There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.
