early Fisher X-100 power light went out - replace with ...?

Slightly less bright, not significantly. I used an old one out of my Pioneer in a pilot lamp for a console amp project just to knock the brightness down a bit. Its still got plenty of glow to it.

Heater voltage is worth a measure. Those lamps are nominally 6.3 volts, the higher you read the less the bulb is going to last.
