Fender® Capacitor Kits
for Vintage Fender Amps
 


All of our Fender Capacitor kits utilize premium F&T Capacitors for the filter section, and Illinois Capacitors for the preamp section.

Capacitor values have changed slightly over the years due to changing manufacturing standards.   5uF has been replaced with 4.7uF.   20uF and 25uF have been replaced with 22uF.      70uF has been replaced with 80uF.     In all cases, 25uF and 50uF have been replaced with 100uF bias filter capacitors for better bias stability and less hum.

Due to improvements in technology, new capacitors are about 50% smaller than original capacitors.

Disclaimer:   Fender occasionally made changes to designs which are not consistent with the model version on the tube chart.  Especially in the "silverface" years, the internal designs sometimes do not correspond with the schematic for the particular model version shown on the tube chart.    It is recommended that the values of the filter capacitors inside the capacitor housing beneath the chassis be checked and verified before ordering a specific capacitor kit, to make sure that your amp wasn't one that did not adhere to the schematic.

Warning:   Tube amplifiers contain high voltage which is stored in the filter capacitors even after the amplifier has been turned off.   Always unplug the amplifier from commercial power, and discharge all filter capacitors before working on the amplifier circuitry.   If you are unsure about this procedure, we strongly recommend that you leave your amplifier in the care of a professional service person.
