Barry,
Have changed those caps twice if not three times. Everytime I put a set
in, someone would say that they must conform to a spec that those I just
put in did not meet. If necessary,k I can buy a new board from TT as
the current board traces won't ake another swap. I'll keep it in mind.
Thanks for your advice.

Sounds like it could be the power distribution board electrolytic caps
needing replacement.

My Orion has a problem in that it will reduce power from 100w to approx
25w primarly on dits during cw operation, not all dits, just one or two now
and then if it is in a failure mode. Of course this is not consistent.
SSB operation and both receivers work well. When it fails the ALC does not
illuminate and there is no audible click from the relay on the A0 board.
Typical conditions/settings are as follows: Keying- Internal, external
or straight key. Two different DC supplies tried. QSK delay=17%, cw
weighting 100 (range 50-150). Antennas: either of two antennas or dummy
load. Keying speed usually 20-25wpm. CW rise time 7ms
If someone has encountered this I would like to hear the resolution.
To add to the mystery, another condition exists, but am not sure if it is
my rig or all Orion I's . Setup- reduce power to 1-5 watts, send a few
characters. Increase power to 100w. Perform a key down. My rig takes
approx three seconds to reach 100w. Normal?
Subsequent key down operations immediately goto 100w.
Thanks for you time,
Van
