Hi Jim
It's not a repeater amp.
When the amp in line it acts more of an attenuator for the receiver.
There is a "Guardian Electric 1365 series" relay used for TX/RX switching.
With a multi meter i get 16.5 ohms across the relay n/c contacts doing an in
circuit test.
I shell look on the net for a suppler of the relays any ideas ?
I have not found a circuit diagram anywhere for this amp either...
Regards
