Collins folks:
I recently acquired a 30L-1. After some cleaning and painting, I put it on
the air with my KWM-2.
It indicates about 1700 volts on the plates and my W-4 meter shows 500 watts
out.
After a week or so, I began to notice a sharp cracking noise.perhaps 2-3 per
minute.
The plate meter moves slightly with each crack.
Thoughts?
Thanks and 73,
Mike March K4QU
