The IF output available at pin 15 is grounded through resistor R1. Inductors L1, L2 and capacitors C4, C6, C7 forms the tank circuit for the ICs built in oscillator section.

The stereo multiplex section uses three tubes. It is somewhat crowded, but still manageable. The board is slightly larger than the AM PWB. However, it may be of interest to recount the experience of a full power Class B metropolitan FM station in adapting its facilities to include this mode of operation. The circuit board for the FM tuner and stereo multiplex section was completed today, as shown below. We do not believe it is necessary to repeat here the various criteria surrounding the FM-stereo system permitted by the F.C.C. Music Production for Emerging Audio Formats.Audio for Virtual and Augmented Reality.Once the 2 channels are switched togheter (mono), the noise signals cancel each. The cause of this effect is that in stereo reception the biggest part of the noise in the right channel is in opposite phase with the noise in the left channel. Archiving, Restoration and Digital Libraries This fm stereo noise suppressor circuit is to be used when the reception of far FM stations is bad but improves when you switch the radio receiver to mono.
