Mike:
I had this problem with the same receiver. It is the line bypass caps.
One or both are no good. Replace with 1600 volt discs and your problem is
solved.

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

Aha! That might be it. Better (more logical) choice on caps nowadays
would be the ac-rated X-Y disc caps. Available at Mouser, Justradios, etc.

Yes, Gary has a good point. I didn't expect they placed the caps
behind the fuses, most manufacturers had them right at the line
cord entry!
