Sirs:
Please see: http://www.anthonywelsh.com
Tony has two different vacuum relay types for sale
with coil voltages from 12 to 24 VDC.
Additionally, in my new tetrode amplifier I am using
two Jennings TJ1A-26S vacuum relays for QSK,
the leader with 47uF/50V~2.2KOhms in parallel, and the trailer
with 10uF/50V~100Ohms, 2W in series, with 1N1004's
as swampers on the coils, which leaves me with 5400 microseconds
of overlap so I don't fry the tube.
Oh, everything works great until I get on 17 meters. Talk about
hotel RFI: I think things got serious when I saw the night clerk
running around the courtyard with his hair on fire.....
