I think I've already found the guy you're talking about. He sells rebuild kits, LED mods, and specific replacement transistors (among other things).
This seems like a project that will fill plenty of my time without costing me an arm and a leg. I'm trying to give myself something to do that will fill my need for tinkering without messing with any of my main gear.
