I have a couple of Polytones - somewhere I think I have some documentation. I will try to find it and scan it when I get a moment.
thanks, that can be great...absolutly no rush with it.
i was wondering what results i would get, if i used only the preamp section-(has a couple of 4558 and tone circuit) only,and drive it with anykind of power amp of the same dissipation...would u think ill get very similar results -or not so close to the original? (the polytone power section uses standard bipolar transistors amplification).interesting expiriement...
