Hi there,
I recently acquired a Conway Electronic Enterprises Model PS-1 Regulated Power Supply. It is very very similar to the PACO B-12 but I think identical to the EICO 1030.

Here are my observations.
The Bias supply seems to not be providing voltage from either the pos or neg terminal, but seems to accurately provide positive only voltage when measured between the pos and neg terminals.
The Heater supply works fine, as do all the other heater lines that feed the tubes inside. In fact all voltages out of the transformer seem good.
The Regulated supply does not appear to do anything.
The build quality is excellent and all the components are original (ie over 50 years old) so I figure I'll be swapping out the electrolytic and wax caps, but my understanding of this circuit is incomplete and if anyone has an idea of where I should I should begin I would be very grateful.
