Agreed on all counts. Several years ago, an engineer in the Alpha
booth told me they use Gigavac. I've been using Gigavac as replacements
for my TenTec amps for about ten years. I bought them direct from
Gigavac under their ham discount program, and I still have a couple of
new spares in my parts stash. I don't remember the last time I had to
replace a T/R relay -- I'd guess at least 5-6 years, and my operation
is 90% CW. I do NOT usually do QSK with those amps though, because of
operating speed, the complexity of keying loops with SO2R operation,
and not wanting to have to replace a T/R relay in the middle of a
contest.

Jim,
If you're interested in a premium T/R relay, Gigavac makes the GH-1
model
and is identical to the Kilovac HC-1 and Jennings RJ-1, all of which
have
been time-tested over several decades.
Gigavac sells direct to us:

Or, check with Alan Bond:

You'll need to specify coil voltage as all three vacuum relays are
produced
with several popular voltage ratings.

Subject: [TenTec] Replacement output T/R relays for TT linear amps.
Greetings to the group.. After years of QSK CW operation, the output
T/R
relays in my TT Centaur 411, and Centurion 422B are in need of
replacement.
When requesting parts info from Ten Tec, there have been no replies to
my
emails. Does anyone have a generic source (Mouser or Digi-key for
example)
and part numbers for the appropriate replacement relays?
Tnx.. 73, Jim W3KA
