Hi,
I'm recapping one of these series II units and thought the neon lamp was gone.
However, now I find that if line voltage is increased to 120 vac, the lamp will light.
So, i figured the lamp had a bad solder joint or maybe the resister in series with it had changed spec.
measuring the resistor gave a reading of 30K, on the money.
The Voltage coming to the lamp after the resistor was 110 VAC.
So, figuring the lamp had aged, I could extend it's life a while by dropping the resistence of the 30K resistor.
I'm finding that no matter how little parallel resistance I introduce, the lamps lighting Voltage seems to remain tied to the line voltage of about 118VAC. (a 2 V drop after I added the parallel resistor.)
It gets a lot brighter, so more current evidently, but the voltage it receives after I paralleled resistance is much higher now, maybe 115VAC.
I'm sure a new bulb will probably remedy this phenomenon, but, I'd like to understand whats going on....
This threads a bit stale, but seems relevant.
Any ideas?
Thanks, Robert
