    Does anyone know where I can download or purchase a manual (schematic) for FPS-101 power supply.
    I have a FTDX101 and the power supply is dead. I also need some info on the 15 amp fuse in the back????
    Is it a breaker or a fuse...won't easily come out...shaped like a switch but has a white cylinder inside??

    Had lightening strike near my QTH and the radio now won't come on...120v in but no DC on any pins...FPS-101 is dead.....

    Photo shows that Yaesu used common appliance industry resettable Thermal Circuit Breaker.
    Reset can be Push button or Rocker.
    Example: TE W-28 series (push to reset, thermal circuit breaker)

    I have not seen a Service Manual or Schematic diagram for the Yaesu FPS-101
    Obviously, given it’s size and weight, it is a Switch Mode (SMPS) Design.

    The Yaesu FPS-101 Power Supply supplies two (2) DC Voltages to the Transceiver.
    50 VDC (for PA) and 13.VDC for remaining control/receiver/transmitter circuits.
