I completed my mockup of the PA driver stages.
as previous post:
- used MPSH10's in all stages.
- Used FT37-43 toroids all wound with 10 turns 0.25mm wire either tri- or bi-filar according to original Sch.
- Bypassed all emitter resistors with a 220pF cap.
- swept from C80 input to T10 secondary (as wound)
Result is a very flat response. Better than 1db from 3Mhz to 54MHz.
