Looking any info on this model. Got it for $7 and contrary to the post-it note it works fine. It's odd in that the phono section is tacked on the back of chassis almost as an after thought.

Sorry, can't help with a schematic. As far as the phono preamp - - they probably kept it as far away from everything else to prevent hum/noise. When receivers/amps were designed for ceramic phono cartridges - which had about 1/2 volt output - the preamp stages weren't as critical as those designed for "modern" magnetic cartridges - whose output is only a few milivolts, thus subject to hum/noise.

Are you 100% sure it's the phono preamp? It might be the mpx for FM Stereo I would need to more pics of the back of the unit to make sure

That makes sense. It has two trimmer coils on the piggyback board.
