[R-390] Blowing B+ fuse

[Barry]

I finally got a couple of 1/8A B+ fuses (SloBlo) and tried one of them.  The
radio played for about one minute and blew the fuse.  I was running a 1/4A
in it before this.  I assume the 1/8A fuse should be sufficient and I have
something leaking somewhere, right?  I replaced all paper caps, but not the
electrolytics (yet).  I assume leaky bypass caps is the first place to look?
Any other suggestions?  My other R390A is a "single-fuser" so I don't know
if the B+ line is pulling more than 1/8A or not.

Thanks,

Barry
