[R-390] F102 FUSE BLOWING

[rbethman]

Bill,

    Walter gave you very GOOD advice.

    I would like to add to it.

    Check the tubes in the Audio deck also.  I had mine blow the same fuse.
Look on the board underneath the Audio Deck.  Look for overheated and
possibly discolored resistors - especially the first one, a 2 watt job.

    That's what I found, and the cause proved to be an audio tube shorted.

    These are lot's of fun to use and work on.

Good Luck!  And keep us posted on your efforts.  Between the lot of us,
we'll get you back up and running.

because I loved them when I was in the navy. Figures that I would have
problems right from the start. The F102 1/4 amp fuse blows. I need some
direction on where to start and who is a good source for parts to replace
all the bad ones that your going to tell me I need. I'm not a real expert
when it comes to repairing radio's, but I'm will to give it a shot.
Especially don't really want to ship this for repair, just to have it
destroyed en route.
