Hmm. Assuming the circuit is wired as shown, the first thing that jumps out is that the B+ supply is shorted to ground through the primary of the coil (lugs 2 and 3). Assuming that that coil has continuity (not open), resistor R3 would be really smokin' (assuming it's 1/2 watt rating). What voltages do you have at the top of filter caps C3 and C4?
