The other R390a is an original Collins single fuse model. I'm going to
install the separate B+ fuses but the question is does this effect the
value of the radio? I was thinking of putting the fuses on a bracket
inside the radio as opposed to drilling holes in the rear panel.

The easiest installation for the added fuses would be to wire pigtail-style 
leaded fuses on unused terminals on the filter capacitor sockets under the 
audio deck.   Neither hole drilling nor mainframe wiring harness hacks would 
be necessary.

The audio deck would have to be removed to replace those fuses but that 
should pose little hardship because changing B+ fuses should be a rare event 
indeed.
