I pulled the transformer from the chassis and opened the clamshell, removing both halves and carefully sliding the wires from the hole. I checked it again under power (without a load), and there is definitely leakage between the primary and secondary against the core. From the secondary to the core was around 25 volts! But I have since located a 116 chassis for parts, and the transformer tested good. So just waiting for it to arrive. I can probably get the missing driver transformer from it too
