Mr. Tom Lee was exactly correct.
Many thanks also to Bob AH7I, and
John Kidd from Australia for more info
and details.
10 K from INPUT to BIAS, .1 uFd
from BIAS to COMMON and 10 uFd on
the OUTPUT, similar to what one would do
with a common low-V regulator.
The isolation transformer, bridge and
47 mFd filter is supplying ripply 180V
peak to the regulator device.
A nice, clean and steady 135V is
running the receiver.

Gentlemen like you continue to prove
that my confidence in our community
is well-founded.
