Hello, I want to modify this amplifier that i bought in a flea market into a Guitar amplifier, is a full germanium transistor, that work at 9/12 volt . Is stereo so i'm thinking about use One Channel for high input and one for low, but i wanna drive only one speaker. Can help me for modification? Tnx

Hello, if I wanna sobstitute power section of this schematic,with a IC poweramp, what part of circuit i've to "remove"? (I not think is all things put after R10)
tnx in advance

Hello I'm new here, and new in building amp, but i've some experience in pedals, so I've a question.
I will build a orange cube 20 i've found the schematics in net and I hope are right I will build only with clean and overdrive sound no tremolo.
I've remove from scheme the thing i not wanna to build, and I hope I've do it right.
I can use a normal dual trasformer 220 (i'm from Italy) to +24/ground/- 24 in diagram is 24.5?
Other question, if someone had a all transistor (no IC) similar or most simple with more common transistor and with only one current need like 12 15 18 24 or 36 can post or send me the schematics?
Thanks in advance
