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
