Took a quick look at the schematic for a zenith 775B. The pilot lamp is a part of the heater string. The string is operated at 2.5 volts. If the base is screw-in I would try a #41 lamp. If it is a bayonet base then a #43 lamp. Both are rated 2.5 volts and 0.5 amps. Hope this helps. Take care and BE HEALTHY! Gary
