There is no mechanical adjustment on the relay. I think the screw you are
talking about holds the coil in place. I have had a problem with a relay of
that type becoming magnetized. Try reversing the coil leads, that may cure
it. 73, Dan, N5AR

Hope someone on the list can help with information about a vacuum relay I
have.  I'm working on getting an LK-800 amp back in good working condition,
and one of the problems it has is a T/R vacuum relay that won't go back to
receive after transmitting.  If I tap on the relay, it does go back to
receive.  The relay is a Jennings RJ1A-26S.  On this relay is a screw that
looks as if it is for adjustment, but I don't know what it adjusts.  I'm
guessing it has to be either contact spacing or spring tension.  I hope it's
for spring tension, and by adjusting this screw I can put a little more
tension on the spring, and it will return to receive when finished
Just thought I would check here and see if someone knows what the screw is
for before I start turning it, not knowing what it is supposed to do.
Thanks for any info.
