… I forgot to explain that this circuit uses the converter twice (RF & AF) without IF amplifying – may be the amplification – depending on the location – is not sufficient: here are three versions of additional amplifier environments (sorry for the poor quality, but I haven’t found all the 3 old images on my actual PC – maybe a former HD crash – so I scanned a DIN A4 page with these printouts ):

It’s a 1-stage-amplifier as one Lectron block with the cable/plug (instead of the earphone / earpiece) with an input transformer (which appears around 1965 in Lectron patents!) , one Ge-transistor and different loudspeaker combinations. The middle one is a special one and contains a “transformer” with one coil and a tap at 50Ω; for the speaker and a stereo socket for stereo headphones of 2 x 32Ω; wired for mono parallel. The third one uses a universal transformer and a special “crossing” block.

Thanks for reading & don’t forget: all known and individual blocks at: http.//www.g-stabe.de/lectrony.htm
