Subject: [Amps] switching cavaties in the AM-6155 Amp
Hello to all........
Has anyone modified one of these amps' power supplies so that it is possible
to
just switch cavities
when moving to another band.....for instance to QSY from 144 mhz to 432, etc.?
Thanks,
Tom

Tom, I don't switch cavities, but I replaced the Stand-by toggle switch with a
'Center-off' toggle to switch between two bias voltages. A separate board
behind the front panel containes the zeners and resistors.
