Princeton Reverb Reissue Modifications

$ 59.95

One of Fender's most classic amplifiers remains a favorite to this day and the Princeton Reverb Reissue is perhaps the most successful of the reissue series. Our mods take the PRRI back to the glory days of the blackface era and adds a couple of the most famous mods done to this amp over time. There is an unused power node in the Princeton that many think Fender did on purpose so it would not compete directly with its big brother Deluxe Reverb. The phase inverter in your Princeton Reverb Reissue shares it's power supply with the preamp tubes. This dulls the sound fed into the power tubes and doesn't fully allow the amp to shine it's perfect tonal light to the world. The good news is Fender left the appropriate power rail for that phase inverter in the design even though it goes unused!

But not for long... 

Our complete mod kit comes with full color instructions and allows you to change the power supply of the phase inverter to the unused anode in the power filtering circuit. This mod is commonly known as the "Stokes mod". It also changes the phase inverter tube from a cathode bias to a fixed bias, known as the "Paul C." mod. These mods work wonders to increase clarity and clean headroom, increasing the overall output of the amplifier with more depth and added transience.

This kit also upgrades components in the tone stack to higher quality metal film resistors, WIMA and MICA capacitors for tonal improvements and improved efficiency in the circuit.

Included in the kit are all of the components necessary to to get your amp in top shape and the detailed instructions to make the changes easy. If you have a basic understanding of electronics and soldering skills you can do these mods in a couple of hours.

*Recently we have made the decision to switch from F&T capacitors to ARS capacitors. ARS capacitors outperform F&T capacitors with a lower ESR, a higher temperature rating of 105c and is located locally in Los Angeles, CA. We're working to update our product photos as soon as possible. Feel free to contact us with any questions about this change that you may have. 

"Have us Install" price includes parts and labor. We will bill you return shipping upon installation completion and which will be comparable to the cost of shipping it in.
