Hello, all. I'm a new member and I believe I own this amp now (don't know why I did this to myself). Hoping Kennymc75 replies or someone may be able to help me w/ contacting him (don't see a PM option).

Thanks!

Or start a new thread for your amp, and specify what the issues are.

Hey Ethernaut ,

That is indeed the same amp. John Sawyer loaned it to another aspiring steel player and it died on him. He brought it to me to see if I could get it working again. At the time I had no idea what I was doing hence seeking help on the forum. The problem that I figure is a short in the amp section. I really didn't have any experience with amps at the time but I poked around on it for a while before I gave up. There should have been some new output transistors in the back of the amp. Some other parts blew off the board at one point and I hope that I replaced them with the proper ones. Anyway since then I have had much better luck with amps and have learned quite a lot. If I had known then what I know now I may have got it going again. Anyway I hope I put it back together well enough that you can figure it out. Good luck
