Hey sluckey,
  Do you remember doing a layout to convert a Princeton reverb to cathode bias and still use the trem?I can't seem to find it anymore.I want to do one but can't quite remember how.Old age is settin' in!

Look at the layout in this pdf (not the schematic)...
http://www.el34world.com/charts/Schematics/fender/PRINCETON_REVERB_AA1164.pdf

1. Remove the wire from the left lug of the Intensity pot.
2. Ground the left lug of the Intensity pot.
3. That's all.

Don't forget to put the resistor and cap under the PA tube cathodes, or you'll get a surprise!
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
