The + 12V power lead to my B40 fell out the back of the unit at some

panel was blown, as well as the 0.25 amp fuse of the same size on the
back of the B40.

I know the purpose of the panel fuse is to protect the wires, and the
B40 fuse is to protect the instrument (I think). Can I safely use a
0.25 amp fuse in the instrument panel and maybe a 0.5 amp fuse in the
B40? (The B40 is the only item on that fuse; the radio, LX and 302
have their own.)

Btw I've checked the B40 manual and can't find any mention of fuses.
Is 0.25 amp the correct fuse?

Thanks

I don't see how the B40 fuse could have been blown if the power wire
was disconnected. You may have another problem. If you don''t find
an answer on the B40 fuse size call me at home (leave msg) and I'll
check mine.
