Heya, I need a replacement bulb for the power light on a Heathkit AD-2002. I opened it up and it has a small cylindrical (perfetly flat on the top and bottom) soldered to the PCB. On the section of the PCB for the bulb, it says "PL-1" I have not been able to find what bulb a PL-1 bulb is online. I have run accross a couple other Heathkit conversations referencing the bulb, but no where stating the specs of the bulb, or anyone selling them or any information on compatable replacements. Someone has to know what I need here.
