[Boatanchors] Screen Modulator

[Glen Zook]

Look at the screen modulator schematic from Herb
Brier's column in Popular Electronics that I sent you.
 The circuit is very similar to the SM-90 but it
doesn't use a transformer.

Or, is there a easier way to couple the stages? The
SM-90 only uses two tubes and 14 resistors & caps, so
it would be easy to duplicate - except for the
transformer. . . .
