Relays are certainly a possibility, Al, but for a nine band amplifier
things get a bit complicated. My latest project ( 90% completed) is a
duo – band 80m/160m amplifier with a pi– L tank circuit, and for that
I am using two DPDT vacuum relays, each of which cost over $100.
Scaling that up to a nine band amplifier doesn't seem very practical
