Thanks for the responses! I have the wiring schematics, but the problem I'm having is someone had clearly gave up an attempt at rewiring or modifying the chassis, so it's not matching the schematics anymore. I just want to make 100% sure I'm placing the right Loctal tubes in the correct sockets, then I can fix the jumbled mess underneath from there. The Type 80 and the 42s are obvious, but the loctals are less so and I just need a sanity check.
