See <http://www.somis.org/QSK922.html>, Rich Measures' article on vacuum
relay QSK. He uses a reed relay for the input and an RJ1A or HC-1 vacuum
relay for the output. I have used a similar circuit in at least three
amplifiers so far, and it is ABSOLUTELY SILENT if you follow his advice to
use silicon rubber to mount it and thin pieces of copper foil to make the
leads. Foil works better than braid, becasue the braid wicks solder and
ends up rigid.
Well, I'm perplexed. My braid connections are not rigid, I used a small
vacuum relay for the input side, and absolutely silent is never a term I'd
use. Maybe I could have done something different, but it's hard to know
what....
