Re: Chinese valve FM receiver kit
It's a variant on the quadrature detector. THe multi-grid valve is used as a multiplier and its inputs are the signal and a phase-shifted version of the signal, shifted by the input coils and capacitors.
There won't be significant limiting so it'll receive AM as well.
Oh boy! what will they sell next?
