  • Heater and High Voltage both "soft" start

  • High Voltage delay timer:  HV cannot turn on before the tube is ready
    Cannot apply drive without HV: PA kept in STDBY (No operation is possible without HV)
    HV plate line is fuse protected

  • The HV transformer protected by magnet circuit breaker (overcurrent breaker)

  • Control and screen grids are overcurrent protected (trip circuit)

  • Blower delay timer:  Blowers run after PA is off for better cooldown

  • Built-in coax relay sequencer:  Separate exciter & tower relay/preamp box outputs

  • Coax transfer relays (depends on the order - contact to discuss)

  • Available also as RF Deck only; complete except for HV supply:  Requires 3KV @ 2.2A
