[Boatanchors] 51J4 schematic

[bill.riches at verizon.net]

.  I picked up a clean 51J4 that I rebuilt for myself and it is working
fine.  I would like to find the correct schematic for it.  It is using 6BA7s
for the mixers rather than 6BE6s and a 6BZ6 for the RF amp instead of the
6AK5.  The correct tube numbers are marked on the chassis.  I checked with
Howard and he said he never saw an R-388 or 51J4 like mine.  The only 6ba7s
that I have seen have been in a 75A3.  Any ideas?
