An incredibly easy modification to your Princeton Reverb to greatly improve its tone, clarity and balance.

You would think someone would have thought of this before !!! No loss of ANYTHING only a gain in great tone.

Replace the Phase Inverter/Vibrato tube with a special tube having half a 12AX7 for the vibrato and half a 12AU7 for the Phase Inverter.

Since there is no gain in the Cathodyne Phase Inverter you can get a great improvement in tone and response from the 12AU7 type stage.

Returning to stock operation is too simple for words.

This is a Do It Yourself Project (DIY) All plans and layouts are included in the download. Plus safety instructions.

You do need to know how to work on a tube amp to do this little mod.
