Hello,

I'm sorry if you've already talked about that but I got the first head version that's giving me troubles. I have the gain and volume pots that doesn't work like they should: sometimes they just cut the amp volume to 75%, or 30%... Just depending. Sometimes they just work fine and just like now, for the last week, my 100w sound like 0.5w...
Instead of throwing it away, I decided to open up the beast and maybe change the two pots. All pots look the same with "0B10K" written on them. Have someone already checked those pots?
Could it be the ALPHA RV112FF-40B3N-22F-0B10K ?
I just found one seller on "alipress" that has those but I don't know if that's the ones I should get...
Any suggestion for you who already tweaked the amp?
Thanks in advance
Cheers

10K linear pots

Reflow solder connections to PC board,  often develop hairline cracks on existing solder connection to Potentiometers, then add a small drop of Caig Deoxit

Remove and reinsert the front panel ribbon cable connection to DSP board

Dear admin

Thanks for your fast reply.

Do you know a place where I could get them (internet)?

Searching through amaz and the bay, I just found those
https://www.ebay.com/itm/124735657832?hash=item1d0ad31768:g:W4wAAOSwNx1gqAkZ

But they are B10K and not 0B10K. I think that the 0 is important though...
If you had any link, that'd be really great...

Thanks in advance

Contact your local Roland/Boss Service Center

Some may sell you the parts

But around 2007, Roland/Boss initiated no longer selling parts to customers - only official qualified service centers nay obtain parts

But Amplified Parts or Parts is Parts may have them
