The MA230 is mostly solid-state, and I don't work on solid-state units. However, the output section is tube and I can service that part of it. If you want someone to check it as a whole, it might be better to find someone who can do that. If you want, I can test the tubes and lube/clean the controls.
I live 6 minutes from where you are. You and I live in the same neighborhood. I want to check with you first.
