The chances are very low because the symptoms you are telling us, are
typical for blown caps or transformers, when the SRSG suddenly stop working
well, the timing gets incorrect... Which is caused by blown transformers /
caps. Remember that only checking the capacitance of the caps is not very
"useful" because capacitance could be fine but the caps are failing under
load conditions...

Thanks guys for the input. Sounds like I'm the dummy!
I hope I didn't run long enough to due permanent damage. It was run that
way for only a few seconds, three times. The caps were not warm nor had any
visible anomalies. I'll check the MMC value tomorrow and the transformer
output using a jacobs ladder. Everything is at work so I'll have to wait
until tomorrow.
Thanks again. What are the chances Imay not have done permanent damage?

Very Bad idea. When doing such Experiments you have to use at least a
dummy load in Form of halogen bulbs, which replaces the primary. When you
simply Run it without secondary, you kill your caps and neon, i think
thats
what happened in Your case.

Betreff: [TCML] Sputtering Gap
Datum: Mi., Mär. 26, 2014 21:25
Could really use some help.
Just completed a new 15/60 NST powered coil with a SRSG. With the tank
circuit completely wired and the secondary removed I thought why not check
the operation of the rotary gap. The first time I powered up it ran fine,
firing smoothly up to the max variac setting.
Subsequent power-ups resulted in the gap sounding like gun fire. The
safety
gap on the SRSG is firing, the arcs at gap alignment vary in intensity and
there are smaller arcs running around the conductor ring on the disc.
The rotor is 5" diameter with four 1/8" carbide electrodes turning at 1800
RPM.. There are two stationary electrodes on the front side. Electrode
spacing is .030" per gap.
Thank you,
Tim Flood
