I have a Hammond AO-43-1 converted to a Tweed Deluxe that a friend and bandmate built for me years ago and it's by far my favorite amp. Unfortunately, he passed away so I can't ask him about a new build. My question is can this be done/has it been done before? I have seen where people add reverb to the common Carmen Ghia/tweed deluxe type circuit, but I'd rather use the extra tube socket for vibrato than reverb if that's doable. My experience with tube amps thus far has been limited to trouble-shooting, replacing capacitors/electrolytics and basic circuit mods, but I was already close to ordering a princeton reverb kit from mojotone. If I can build a blackface princeton (nonreverb) from my Hammond AO-43-1 it would not only save me $500 but it would be more unique and, based on the tones I get from my Hammond AO-43-1/Tweed Deluxe, I'm guessing it would sound great. I'm hoping someone's already done this and there's some schematics/layouts out there somewhere but I've tried searching online and have not found anything. Any help would be greatly appreciated. I am new to this forum and this is my first post.
