so I shorted out the relay to simulate having no B+ relay at all. Also I switched the polarity of the silicon diodes to the band end facing towards positive. I powered it up and no action whatsoever. No pilot light no tube filaments. But the HOT damper and I think the shunt regulator tube filaments are glowing. I think the diode polarity is wrong, or i killed the filament winding on the power transformer.
