The 80 acts like it is shorted?  If you see flashing inside the 80, shut it off immediately!  It is likely that there is a short loading the rectifier down.  The most common cause is shorted electrolytic capacitors.  The originals of this vintage almost never survive and will short.

All caps on antique radios should be replaced with new, modern caps, but replacing the electrolytic caps used as filters in the power supply is an absolute must, especially in radios from the 1930s.

It's a shame if the 42 is too weak to use.  Globe 42s are way cool in my book.  They are the genesis of what became the 6F6, a common pentode (non-beam power) audio output tube.  ST type 42s are common, but globe 42s are rather rare and a good one will command some money.  Save your old one for display.
