Don't you have a mixer for your music production?
The output could be used and the master fader would be the pot.

yes thats true, but i want amp to be used for my bass i have guitar and this wil lbe for bass, i have big 15 inch cabinet so i want to use it with that
Yes, OK, but for now we are just trying to fix the amp.
You need a good signal path.
Anything else can be done later. 🙂

i can also connect output of one of my guitar pedals and control input that way on empty preset
I would take a fixed source.
Music into mixer, mixer into amp.
Or output CD player, or output smartphone, anything that has a volume control.
You can't play guitar and measure the amp at the same time. 😱

no guitar playing i played music over empty preset of the pedal its like using only its volume and eq. btw i dont get that buzz at all but a usual pedal hum like white noise
just noise like any other amp, it is more noticable because is working with guitar pedal that has its own noise xdd but when i touch ground nothing happends so it is working this way, i want it to work the usual way
Congrats!
Sisters and brothers, this is a historical moment.
sg97 fixed his amp after (only) 868 posts.

btw i dont think pots i have are any good i can measure constant resistance you mentioned, so i have to buy new one
Hugo ... smarter? Your suggestion is bang on.
You went the distance here.
Hi sg97,
Never use 1/4" phone jacks for speaker connections. Those are a great way to blow up solid state amplifiers and they come out easily. The Speakon Hugo suggested is the very best choice.

I've been busy lately, but I can't help but express my admiration for Hugo's patience. Bravo!
Bravissimo!!! 🙂

Change the jack!!
You have no idea how many blown power amps I have repaired over the years due to 1/4" speaker jacks. They short as you pull them out, and it isn't uncommon for them to come partially out - shorting. Speakons cannot short, and they lock on top of that.
