Bad design.
NPN switch from the 6.3 fil power through a 1/2 wave rect, lighting up 3 2 volt bulbs through a 6.8 ohm resistor, as long as ALL 3 lamps are OK, all is fine, but if one burns out, then they ALL go because the voltage spikes.
they sell them in packs of 10, not gonna do it, I can get ultra bright yellow LEDs that run at 2-3 volts in packs of 20 cheaper.
