Hi PL,

You know I've tried adjusting the signal generator all up and down the scale to try to do exactly what you're saying. This thing is just baffling me. It sure acts like my 1st IF transformer is not working even though the internal resistances are reading good and all associated circuitry is good.

How critical are the resistances on the 1st IF transformer? I have another IF I would like to slave in to see what happens but the resistances are 22ohms and 23ohms primary and secondary. My schematic says my existing 1st IF is .5 and 11.5 respectively.

Thanks,
Johnny
