PYE 1964 British Germanium Transistor Mic Amp Mixer Unit Type 843803
I sold this unit a while ago to a recording studio owner in Chicago, he was very pleased and mentioned how it sounds great on early ribbon microphones, at the time i had many valve Vortexion mic amp mixers so thought this sounded a bit thin, after it sold i immediately regretted it, the distortion sounds very useful for vocal effects. In this video you will see the technician explaining the circuit and going through the unit with a brief description. I will stick the circuit diagram on our website for download.
