Sorry for the late reply, Doug. Assuming your are asking about F2, the PTC
fuse for the 12vDC out jack, it is on the main board, directly beside the
12V out connector. You can see it here:

Thanks.  If it's a PTC fuse, at least it won't require replacing, OTOH,
it's not going to protect the external switching device quite as well.

In the other direction, it does look as if there'd be no problem if the
power connector for the P3 or PR6 is plugged into the PTT IN or KEY OUT
RCA jacks.
