tube coils



John,
I forgot: Your diagram shows a TPTG oscillator. The pop sci article is also
a TPTG oscillator. Are most tube TC diagrams of this basic configuration? Why?
Also, with B+ running around all over the place via ground, a fil xformer with
center-
tapped sec might do better at keeping RFout of the filament leads. Use 0.01
caps in
each lead to a grounded center-tap.
