Technics SU-8044 noisy pots
I'm new here and the proud owner of a Technics SU-8044 Stereo Integrated DC Amplifier that I bought new in 1979. It has served me well through 30+ years of vinyl, cassette, CD and now drives monitor speakers a small basement recording studio.
The only problem is that the volume and balance pots are are now extremely noisy when they're adjusted (fine if not moved). I've tried everything to clean them and got some improvement, but they're still too noisy. I suspect they're just worn out after 3 decades of frequent use.
The volume control is a two-gang pot marked "M 250K Bx2" - which I'm guessing is a dual 250 KOhm audio taper.
The balance control is marked "8N3A 200KW" - don't know what this might be - it has a centre detent.
I've downloaded the schematic and I'll take a look at it but, in the meantime, does anyone have any experience with this amp or know where I can get replacement parts?
It's a very well built unit and replacing the controls shouldn't be difficult if I can find the parts.
