Re: Proton AP-1000 Stereo Preamplifier

hi ronpilgrim,
I have the P1100. Tone control (treble & bass) are totally missing. Years ago they have been removed cause weren't working and causing some noise; so it was stored and forgot inside a closet.. I coulnd find the potis... I'm, today, trying to fix it and findin out that even the poti volume is not woking properly .. seen a lot of spare parts around... but I do not have the codes-name for any of those parts.

I think if you find the poti for your pre you could be able to solve your issue... To find out the name of your parts is enough to open the cover and read it on top of the potentiometer itself..

I'm asking could you please pass me on those codes? Potentiometer for volume (is a blue little box with a white label), bass and treble.. it can be a very great deal of help...

Thank you
Alex

I recently picked up one of these and the bass control does not do anything. I saw a post at Audio Karma about this problem, but no resolution as yet. Anyone out there have this problem and know how to fix it?
Thanks!
