+430 volts dc.
If a close reading is not obtained, check V7C, C17 and C37, R84 and
R85, and L1.
Junction of C18D (C38C) and R68. (fig.
If a close reading is not obtained, check C18D and R67,
+320 volts dc.
If a close reading is not obtained, check C17C, C17D, (C38C),
C18B, R49, R50, and R51.
+225 volts dc.
If the indication varies by more than a few volts, adjust R43. If
adjustment of R43 does not correct the reading, check V8, V9,
and V10 and associated circuit components.

The dc resistance data (table 73 below) is provided
the sole basis for discarding a transformer or coil
as an aid to troubleshooting (sec II). When using the
as defective. Because of rather broad winding
data, observe the following:
