Disconnect the selenium rectifier, it shouldn't be doing anything the way it is wired, but they are prone to leaking and failing in very dramatic ways.
You do need another resistor in series, what exactly that should be depends on B+ voltage and current, so a bit of trial and error will get it close enough. On my 7 tube Zenith AM/FM, a 50ohm 10 watt corrected the voltage.
