In a pentagrid converter the cathode, G1 and G2 (acts like the plate and has HV on it) is wired as a triode oscillator, that's the bottom half. The top half is setup as a pentode amplifier ( this is where the input signal is applied to G4) Wrote: http://www.r-type.org/pdfs/6a7.pdf
So is the correct procedure to connect the freq gen to pin5?
