    Switching input/output, then adding the bias, then if possible, delaying the TX through the menu, untill the other switching is done, is the proper way to sequence for a SS amplifier. It keeps from hot switching the relays.

    On VHF the amp bias is switched off because when on they can create RFI that the local station can hear covering up weak signals...

    Here's your guy. He has been selling Larcan & Harris amp pallets for a while. It would be best, if you could get him on this thread. That way, in the future, the answers will be there.
    Have you Googled the snot out of the subject? I know that there is loads of info & articles on the Larcan amps. I do remember some how-to articles on the Harris amps.
    Please post your findings.
