B12NF/B15NF Schematic (1965)
I forgot I had this – it’s a 1965 B15NF schematic that I redrew. It’s pretty much the same as the 1966 version I posted previously. However, I did notice some differences with the speaker cable wiring, as well as the Treble pot on channel 1 being shown as 4 Meg, instead of 1 Meg. That seems odd to me, but who knows? There may be other subtle differences that I didn’t catch. I’ve included a photo of the preamp section of the schematic that I used as a reference.
