Veronica Stereo Encoder

As you probably know, to enable stereophonic broadcasting, audio channels LEFT and RIGHT have to be specificaly encoded in such a way that FM receivers can reconstruct stereo. This is a low cost, but powerful, stereo coder. Since the schematic is very ‘clean’ there’s no full documentation available. Just note that : * Trimmers adjust 19KHz pilot tone and output levels (see schematics). * Cap. trimmer fine tune the 19KHz pilot tone frequency (from 76KHz crystal).
