I was given some gear the other day. And in the box was 2 amplifiers a working Afterburner tube amp. and the Demco Demon 150. I am trying to find a shecmatic for the demco since it looks like it has been butchered at one point or another. I would like to bring it back to original for use on the 10 meter band when I get my licence upgraded.

I know you don't want to hear this, but here it is. Toss the amp in the trash and make sure no one else can use it.

The amp has no output filtering, it is most likely class "C", and unusable for SSB.

I'd recommend the same procedure for the "Afterburner", whether it's "working" or not.

not quite the answer i had in mind. but I understand what you mean. Well I'm just gonna stick them up on the shelf and maybey use them for parts if I build a clean amp someday. I just have a hard time letting anything "tube" go to the trash.
Also I know there are a lot of better SS amps and radio's available but I enjoy working with the old equipment.

I have seen the schematics show up on ebay in the amp section.  Usually a search for Demco will find them.
