I have an omega matched 120 foot tower and I apparently have a bad vacuum 
variable capacitor. Upon applying more than about 300 watts, the SWR goes off 
scale. Tuning it out and trying again, yields the same thing.

The question is which capacitor is the culprit. These are surplus Soviet caps 
obtained from the Ukraine and, as I recall, the larger value capacitor is the 
parallel one, not the series one. I could buy one of each and switch one at a 
time and have a spare left over. Any suggestions ?
