I found tis circuit in na old documentation from 1958. The circuit uses germanium transistor availble that time and hard to obtain today. The circuit is indicated for phono applications using variable reluctance transducer.
This amplifier was found in an 80s component manual. The circuit can be used for media recovery....
This simple transistor circuit is from a 1950s publication. There were no LEDs at that time so an...
