1st off, thx to everyone for yr thoughtful responses. Believe it or not, I actually feel a little better, so thx! I've got an old set of tubes that I'm going to give a shot. Maybe I'll luck out and the amp will work properly, at which point I'll simply go for new tubes. I'll post an update. Apparently, I wasn't clear (not that it matters), but even If I decided to stop with the hobby (the gear), I'd never stop listening. The gear is the hobby, the music is the passion!
Lastly, I was asked about the frequent fuse changes. I have zero knowledge about this but I HAVE read quite a bit about the RM9 over the years and apparently this 'fuse changing' isn't/wasn't unusual at all! If I understand it correctly, the problem was addressed in the MK II version of the RM9 by a re-positioning of the fuse holder, allowing for much easier access. I never thought of it as a big deal....until now!
