Howdy all,
I have 2 Eimac VS-5 vacuum relays that I would be willing to sell to
whoever wants them.
These are really old I believe and look like they can handle a LOT of
power. They operate on +12 V DC. However, their performance begins to
degrade a bit above about 15 MHz. They work great on 20, pretty good on
15, but not so good on 10 M. On 10 M they look like they are about 100
Ohms with a bit of inductive reactance. They also have an insertion loss
on 10 M of about 0.3 dB.
I have network analyzer plots on both relays from about 100 KHz to 100
MHz.
I don't know how much these are worth. I pulled them from my amp and am
replacing them with newer relays. Other than the high frequency
performance, these things work really, really well (they might be a
little slower than more modern relays though). If you are building a 160
or 80 meter amp and would like to switch a lot of power these would do it.
Any takers?
73,
Jon
