The filter caps for the power supply in these kits are German made F&T caps (Fischer & Tausche – F&T have been making premium caps since the 40’s).  We have discovered that – as far as power filters go –  these caps are electronically superior to the popular Sprague Atoms (the old industry standard before they changed their chemical/electrolytic formula).  They have more accurate capacitance readings and consistently lower ESR (equivalent series resistance). Low ESR facilitates a more efficient & accurate circuit, enabling more efficient circuit function.  As power filters, F&Ts perform BEAUTIFULLY in vintage Fenders.

The cathode bypass caps in these kits are all high quality Nichicon capacitors.  We found a special 'large body' cap that sounds incredible in a vintage Fender!  These caps do a great job in the preamp, facilitating full, detailed, rich musical performance from your preamp tubes.

Dropping resistors for the power supply are included in all ERK kits as a courtesy!

These kits include detailed instructions & diagrams, including the blackface version of the original Fender layout diagram for your amp, when available (not available for all amps).

 

It is common practice for amp techs to replace all of the electrolytic capacitors in an amp every ten years or so.

These caps perform several duties.

  • The filter caps literally filter the high voltage used by your amplifier.  Good fresh filter caps help reduce hum and background noise.
  • High quality caps deliver rich, clear sound.  Cheap caps sound muddy and can cause noises and circuit problems.  This is true in both the preamp and power supply.
  • They keep your bottom end response tight.

The electrolytic bypass caps in the preamp determine the operating & tonal characteristics of the preamp tubes.

These caps wear out & drift over time.  These caps can also dry up & malfunction (especially when left unused).  This can cause serious damage to your amplifier.

Replacing the electrolytics in your amp is considered standard, basic maintenance for a tube amplifier.   10 years is the recommended replacement schedule.  

 

Princeton & Champ note: These recap kits replace the old cap cans with new, individual power filters. We have found the tone, reliability and performance of modern cans to be far below our standards. This also has the optional advantage of keeping the original appearance of the amp! You can keep the original can in place and install the new individual caps inside the chassis.
