After spending hours trying to stop myself, I gave in to temptation & I took the chassis out to have a look. There weren't any initials or dates like I was hoping for, but under a layer of dust on the top of the chassis were labels of which tubes were which in marker. I also discovered a 12ax7 & that it's a 6an8 not 6an7 (I had originally listed 6an7, I think). If you're counting that's:
4-KT88's (Formerly Sunn labeled KT88's, replaced with Svetlana KT88's.)
2-GZ34 (Amperex, left in because they tested fine.)
1-6AN7 (Sylvania, left in as well.)
1-12AX7 (Sylvania, I think. It wasn't replaced. Could have been Amperex? I don't remember & It's too difficult to get to.)
I took some photos of all of this with a disposable camera that I had around, I just hope they turn out. I refuse to take this thing apart again. It was a bitch getting the chassis out & I don't want to risk fucking anything up if I haven't already. I still have yet to go down to the practice space to hear how this baby sounds now. It was spectacular before, so I'm sure it can't sound worse. We'll see...
I'll get the pictures developed tomorrow & I'll scan them ASAP. I hope someone's reading this that'll be able to help me out with this thing. I feel like there's not much traffic around here.
