I have a PB12 unit that just keeps blowing fuses every 3 seconds. Can
anyone enlighten me at to what may be the issue? I have heard that
they blow capacitors. It blew up while it was not in use. It was in
stand by mode.

Best get it to a servicer who has access to Harman tech info and some
experience with these. There are several service bulletins and
modifications that should be considered when servicing this unit.
