Ok but most of the vacuum relays I've seen are 24 volt. Anyone make a 12
volt vacuum realy? I assume I just hook the two relays up the way it's
hooked on the single realy now and just split the tr/rx sections?
Thanks,Don

this amp to use vacuum relays. I've been told that I would need two relays
but really don't know for sure. I've found several vacuum relays on ebay but
need to be sure of what I need to get. One or two? Voltage? ect. I can't
deal with the relay noise in this amp any longer.

the output from the amp to the antenna. The MLA-2500 uses an open frame
DPDT relay to accomplish both of these functions.
