Knight R-100A Receiver dropped dead while listening, and hoping to get
back on the air if only with a "nostalgia" station. The fuse had
blown. No previous problems. I replaced the fuse, turned it on,
the dial lights glowed dimly for a couple of seconds, long enough for
me to say "that's not good". Then the fuse blew again.

Preliminary checks don't show anything visibly shorted.

Any suggestions appreciated. TNX es 73, Mike
