(11-02-2016, 03:07 PM)RadioroslynJust as an aside, the cap on the 6A7 isn\t the control grid it's the 4th grid which is the rf input grid. The actual control grid is grid 1 which is on pin5. 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?
