The 220-ohm cathode resistor on my Baby Champ’s audio output tube also was on its way to resistor heaven, so I replaced it with a zener diode. This resulted in increased audio gain, but distortion at low listening levels, so I’ll replace it with the correct part one of these days.
One can do all sorts of crazy mods to these Northern Electrics and they just soldier on.
What a great little radio!
