Good morning everyone, This is my first post, so I'll start with a short introduction and then my question. My name is Christian and I am new to the world of tube guitar amps or amps in general. I have dabbled with tube radios with mixed success, but I get the basics of circuitry. I have a chassis from a tabletop RCA radio with octal tubes. The tube sockets are all in good shape as is the output transformer which drove an 8 ohm 6 inch speaker. The tube lineup was 35z5, 12sq7, 12sk7, 12sa7, and 50L6. This was a transformerless set. I have it in my mind that I could use some of these tubes, chassis, output transformer, and maaaaybe the speaker to build my first amp.i would like to add a main transformer. My goal would be to build a guitar amp with a very clean sound. If I want distortion and reverb, I'd add accessories such as pedals. I have lots of questions so I will try to make this as simple as possible. With this old radio chassis be something that would be practical to build on to? Can someone provide me with a schematic and possibly a parts list for the type of amp that I am trying to build? Did anyone recommend a good source for a man transformer? I want this amp to be pretty simple. An on/off switch, volume, and tone. I don't know if I would use the original potentiometers or not, but I do have them still. I may also want to swap out the original speaker for a 15 inch 8 ohm. Thank you for any information and help you can give me.
