Hi guys -
Picked up a clean 53-658 a few weeks and started on it yesterday. It's all original and clean under the chassis.

It does not power up on AC and does not register any volts on my amp meter. Tubes test good. Am I correct that the likely culprit is the selenium rectifier? I haven't replaced one of these yet and could use some guidance.
This article suggest installing a terminal strip with 1N4004 diode and resistor between 20 and 200 ohms. Outside of starting with a 100 ohm resistor and repeatedly measuring, is there a known resistor value I should use?
