PROTON 520 schematics
Hi all!
I just wondered whether anyone knew the schematics of this amp, or a link where i could find it ... The reason is that I noticed a while ago quite a big amount of positive DC on the right HP output of my old '91 Proton 520 amp [+1500mV, not bad isn't it?], and, as the trim pot -that seems to be the Ov adjust- doesn't have any effect any more, I wanted to find out if it's the only one in cause or not. I would also like to see how it's possible to turn this 520 into a 520B-like, ie, without any tone or effect key [tone, mono, bassEQ, etc...]. How to shunt them correctly... many thanks in advance to all for your precious help! Tryphon Tournesol |
