Princeton Reverb - Tube Set
These premium tube sets include:
1 Tube Chart explaining the function of each tube position!
2 x Electro-Harmonix 6V6 power tubes. TAD 6V6s are no longer in production, so we have carefully selected our next favorite, the Electro-Harmonix 6V6! This tube is actually very close to the vintage US 6V6 construction and gives the closest tone to a true vintage 6V6 out of all modern production 6V6s that we have tried in vintage Fender circuits.
3 x Tung-Sol 12AX7 tubes. These are our favorite current production tubes, especially for the first preamp stage. They sound great! Big, fat, warm and rich with lots of harmonic detail and a sweet top end.
1 x NOS/NIB Phillips military spec 12AT7 tube. These are the best possible tubes for your reverb driver. They out-perform and usually far outlive any current production 12AT7.
1 x Rectifier Tube. Either a 5U4GB (silverface) or a 5AR4 (=GZ34 for blackface amps). Your choice. It is highly recommended that you stick with the rectifier tube your amp was designed for.
Princeton Reverb amps are 'non-adjustable fixed bias'. This means a single, fixed resistor determines the bias point of your power tubes. No 'bias adjustment' needed, just pop in your new tubes and enjoy!
