During the cw contest my henry 2-kd classic started to act up, no power output
on 40-80 meters and after 3 or 4 seconds transmitting on 20 power drops to
zero. 10 and are normal output . plate current, plate voltage and grid current
remain ok on all the bands and input tuning is normal on all bands. all power
goes thru bird wattmeters and bird coax switches which have functioned fine for
35 yrs. I eliminated all of them with 1 coax and wattmeter into the dummy load,
same results. At no time did I observe any noise or smell from the amp to
indicate trouble, this amp is going to be a pain to remove and open up for
repair so I hope to learn something before that has to happen, any
comments?....Doug, w9iix
