Looking for Princeton Chorus schematic

[NFXP]

Emailed Fender, they only have the DSP version. I'm looking for the first version Princeton Chorus amp schematic. Anyone have a pdf copy?

You are probably looking for Princeton STEREO Chorus. I bet they have that, but not in the same place as the DSP version

Link is dead for me, Enzo.

If that's the one, here's a link.

thanks guys. Yeah first fender sent me the Power Chorus schematic, then the Princeton Chorus DSP, then they said they didn't have the Non DSP version.

thanks JPB that schematic is clearer.

Bonus question: does anyone have Fender service bulletins? there was one for this amp that said to change one of the electrolytic caps in the chorus section in order to get more depth. I owned one of these amps 10 years ago I did the mod and it had good results, now that I own one again I'd like to do that again.
