C'mon, Ryan! Fire up that soldering iron, it'll be FUN!
Do you already have links to BillM mods?
1. install bias pot
2. change input capacitor
3. power transformer upgrade
For the power tubes, I dabbed a bit of clear silicone goo on the ends of
each spring to the retainer plate above, and the chassis hole below. Keeps
them from slipping out when changing tubes.
