Fender Amplifiers have a huge musical legacy that dates from the very beginning of modern popular music. Fender amplifies have a clean tonal character which is not matched by another manufacture in the world. Our Fender full revalve kits are put together after a life time of using and comparing the performance of valves in these amplifiers. The kits offer the best options drawn from original new old stock USA made valves and their modern counterparts. They are designed and put together to provide improved sonic and tonal definition with more clarity out of these legendary amplifiers. Each preamp kit is specially selected for low noise, uniform gain and tonal characteristic. All output valves have been burst tested and matched on anode current and gain.
Volume Reduction Kit 5070Our Fender Hot Rod Deluxe Pentode kit is designed to reduce the volume of your amp by between 50% & 70% . This Kit consists of 2 Yellow Jackets Fixed Bias Pentode operation Valve converters and Two Matched JJ EL84 Output valves.
These Pentode operational converters not only drops the volume of your amp but also changes the operational mode to class A . This provides a VOX style tone with an increased touch sensitive response. The Yellow Jacket Fixed Bias Pentode operation is for amps with fixed bias circuit. So these can be used on other Fixed bias amps in your collection.
These specialized power reduction , current-limiting voltage conditioning adapters converts your amplifier from Class AB to Class A operation and drops output power by using EL84 without modification or rebiasing. These converters for Fixed Bias amps cleverly provide the necessary plate voltage drop and current limiting on the screens as well as blocking the amplifiers grid bias voltage while configuring the EL84 in a Class A.
