[R-390] R-390 Rookie Questions

[carolew]

     I just picked up my first R-390 (not an A). It's a very impressive
receiver. Undoubtedly, I will be peppering you guys with quite a few
questions in the coming weeks. Some will be dumb rookie questions but
please bear with me.

    Here are my first:

    1.  Where can I get a spare set of fuses? What values would you
recommend?

    2.  The bandwidth does not appear to work. The set sounds the same
regardless of the position of the bandwidth switch. Any obvious things
to check out?

    3. What speaker did the military use with the R-390? Currently, I'm
using a generic boatanchor speaker coupled to the set with a Hammond
matching transformer. It sounds pretty good.

    Thanks.
