I am repairing my B&W 51SB-B Single Sideband Generator and need the

Primary 20,000 ohms single plate 10MA DC
Secondary 500 ohms

Hi,
Looking at the 51SB schematic, is the T-201 input transformer
for the antivox circuit the same as one you need?
If so, move that transformer over and use any generic
20,000 Ohm to 600 Ohm transformer for the antivox input.
(You don't need precisely 500 Ohms in the antivox circuit).
The antivox input circuit has no d.c. current at all
in the high Z winding, so any small transformer
will work there.
