Lou -- As I recall, in Rx/ standby/cutoff, c. +120v and in Tx, the
same as the zener V. However, a 922 should be converted from
V.-cutoff bias to R cutoff bias using a 10k - 100k resistor to protect
the unfused T2 from a meltdown if a 3-500Z happens to short. .

Has anyone measured the bias voltage at L20 to ground in the standby
and
operate position on the TL 922A..If so please let me know what you
measured...
