Thanks Lane and all:
You may be right. The local tech reports a problem in a transformer. Also some
scorched board and fried components in what he calls the 160m section. Thats
strange because my host removed his 160m antenna about a year ago and the amp
has not operated on 160 for a long time, and only briefly, because this is a
city location. I have not seen the inside of the amp, as it was taken to a
trusted local tech. It is small consolation that I gave the amp to him as a
gift, but I still feel terrible that it busted while I was using it.
Looks like I may need to bring the whole amp to the USA, and leave my friend
without it...particularly bad, because he just told my what a major improvement
the amp made to his station and referred to his station as "before Alpha" and
"after Alpha" because it was so dependable. He hasnt used the Henry in a couple
years, so we need to try it again.
But the IC756 only puts out 30 watts on 10m, so cannot drive the Henry. I was
in Russian contest on 10m with only 30 watts. My friend is a SSB man and likes
to be loud. Without an amp this station is better on CW.
thanks to all

In the past when I have had similar symptoms it was the plate xmfr shorted.
Both of these instances were Henry desktop amps, one a 1KD-5 and the other a
2KD-5. You need to start unloading, ie, unload the secondary of the plate xmfr
and see if it still blows fuses.

Turned on my hosts amp this morning and tripped the 2amp slow-blow fuse...Got
more fuses this afternoon and same thing keeps happening.
Seemed to shut down normally althought there may have been a problem with a
sticky T/R relay before turning off the amp.
Any ideas what could be causing the 2 amp fuses to blow when turning on the
switch?
Thanks
