Hi,
I see that GigaVac also sells new relays and has a "ham" price if you
have a callsign. http://www.gigavac.com/products/relays/ham/index.htm
The Jennings RJ1A replacement is listed for $69.00
I haven't used one of these or have any affiliation with them, just
saw the relays advertised and your post jogged my memory.
73,
George / KF9YR

When this happened to my Titan (in the last hour of a CW contest) it was
the
main antenna relay (on a board right next to the output coax connector).
DO NOT
buy one from TenTec -- bloody expensive, and you can buy good condition
used
pulls on the net for under $40. I bought two so I would have a spare.
It takes an
hour or two to change it is the original Jennings relay. TenTec later
switched to a
KiloVac relay, which requires a different PC board -- if you have that
one, you
may need to buy one of the older boards from TenTec. And if you buy the
relay
from TenTec, you'll get both the relay and the new board. $300.
Here's where I bought mine. I see that they also sell Kilovac, so they
may have
replacements for the newer relay too.

Another hint. Relay failure can cause transistor failures on another
board that is
under the tube sockets (easy to reach from underneath). Don't run the
amp with
the defective relay to avoid blowing those transistors. The replacement
transistors should be easy to find. I had exact replacements in my
junkbox.
