Seems like your filter choke is open. The high voltage on the 80 is due the absence of load because of it.
Warm or not, if it shows in megaohms....you know the answer.
You can temporarily try a power resistor, just to make sure the rest is working.
As for the choke, try to find the inductance data on it and the current rating. Of course DC resistance means something also as it drops the voltage. If the choke you find has not enough resistance you can always compensate with adding a power resistor in series.
