Protection of pre amps

Relays and sequencers are fine  but do no forget the following !

A look at the circuit diagrams of commercial made preamps SSB ELECTRONICS
and some others , all use BACK TO BACK diodes at the output of the preamp
for protection. Some use a chain of diodes all depending of the tx power.
