Hehe...last time I was watching TV or movies was...cannot remember,
maybe couple of years ago, prefer books...now reading Fritjof Capra
in Russian translation, please, remind me this joke with
famous french artist
DOA is don't-remember-where-stolen schematic from Japanese Web,
it is common classic 2sk389-cascode-"videobuffer"...good shit.
Gain structure:6/12 db trafo-(0/-8),then (+(2/4/8/16)+4db) on first opamp,
then (+10/+18) second opamp...both dc servo'ed.
48 db of gain range in 2db steps and -20 db pad is enuff...
it gives about -8...+60 range in hi-z, possibly to configure
it in different way...
Possibly to use one opamp like on Forsell's site.
Input trafo is mine, 24-25ee lams from Magmet, shield from Farnell...
Here's the controller:
