Maybe a weak 1R5. Also check the connect to the loop ant.
R-20 is a voltage divider which drops the the B+ down to make the filament. Check it's value they can run hot and change value. If it's ok then play w/that resistor that is in series w/the si diode. Lower the value till the filament is @ 1.5v or so.
