Several years ago, I bought Heyboer replacement power and output transformers for my Marshall JMP 2203 100W. I didn't end up installing them and they've been collecting dust ever since. My question is: What sort of amp can I build using these transformers that isn't a 100W amp? Would they work for a 20 to 50W build? Would they work in a bass amp circuit? Does anyone have any other creative ideas to put these transformers to use? Thanks in advance!
