Re: Regarding home made TRF
Neil, It would require 2 stages of 6J5 RC coupled audio amps, which have a gain of 15 each according to the gain tables in the back of my RCA Tube Manual, to fully drive a 6V6 from a regenerative detector. Or use the two halves of a 6SN7 in place of two 6J5's.
Don't forget to audio decouple the plate circuits of the audio amps or you may end up with motorboating oscillations.
John.
