F&T - Blackface Electrolytic Recap Kits
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 (my old favorites, and still great caps). 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 Sprague Atoms, made in the USA. These little guys do a great job in the preamp, allowing full, musical operating parameters for your preamp tubes.
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). These blackface kits are compatible with blackface amps and silverface amps with the blackface mod.
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.
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 two duties.
- The filter caps literally filter the high voltage used by your amplifier. Good fresh filter caps help reduce hum and background noise.
- They also 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.
