My Heathkit HD-1430 keyer died at Radio Rodeo on Saturday.  I found a blown fuse in it.  It functions and draws nominal current when powered from 12 volts.  The bridge diodes measure OK as does the capacitors and neon light on the primary side of the transformer.  The fuse in it is a 1/16 amp MDQ dual element time delay fuse (datasheet attached) which is proving hard to find.  Does anyone have something like that, even in a somewhat higher current?

Thanks,

Rich
