Frank Donovan, W3LPL is probably the world's best source of info on this
type of lash-up. His multi-multi contest station, as I recall, had amps for
each band, with only one power supply. It may still be in operation.

No, you don't need any relays to switch HV; just excite the amp you want to
use. I would highly recommend HV glitch resistors in each RF deck, and also
in the power supply.
