Re: Quad FM3 no stereo
OK - the input to the demodulator is an emitter follower, with its DC conditions set by another emitter follower. Looking at the schematic values, it looks like the input emitter follower base sits at around 5.5-6.5V
You can see why Quad chose the technique they did for generating a mono signal when you read the attached method from the decoder datasheet!
