Well it seems one of my two spare 1B3GT's went bad in storage (did anyone catch me calling it an IB3GT for a while?

). Thankfully my second one was okay.
I also had two spare 6BE6's. The first one had good emissions and life but the grid leakage test swung the needle everywhere. The second tube tested perfectly fine.
Once everything was reinstalled it was attached to the variac and a DMM to measure current and slowly woken up.
No smoke. No nasty noises, no explosions. Current draw also seems to be pretty low. Cycling through the modes all the tubes lit and everything seems okay. We'll let it sit for a while to cook and see if anything happens and then I think it's about time to see if we can get a picture.
