While I ponder the pully, I started on the second chassis. It's definitely earlier and a crustier.
First I pulled the 5U4 and did a power up test. All the tubes lit and I have about 860 VAC on the 5U4 plates.
I'm going to start in the HV box this time around. This one has three 470K resistors in series while the other had a single 2M HV resistor.
