23612362I had this amplifier given to me. I would like to know if there is a schematic for it? there are 6 100uf electrolytic caps. 350volt. one is blown. does anyone know how they they are installed, as to which way + and - go in the circuit? I can't find anything on this amp. this is not the three stage phantom by d&a. to old, might be the first version,has 10 tubes plus a 12at7a audio tube.

It appears the plus side of the caps should go where the wires are and the ground or negative side should go to ground. Should be pretty straight forward. If need be trace the wires back and see if they go to ground or another circuit. That should help you find which way they need to be installed. You may want to get some better caps to place in it as well. And be careful of electrical shock as well!! Would hate to see you in the obituaries!!
