One Solid-State Plug-in replacement for  ( see below)  rectifier tube.

This unit gives you a reliable, solid-state device that will eliminate power supply "sag" and increase the voltage output over a tube-based rectifier. You cant to use it in the device with series connecting filament. (with out a power transformer)

 Use to replace 6X4  or if you have type not listed  -ASK!!!

NOTE: When using this device to replace a vacuum tube rectifier, you should ALWAYS use a "Standby Switch" in the high-voltage circuit to allow for a filament warm-up period in the amplifier tubes! This will help to prevent "Cathode Stripping" of the power output tubes.
