THD YJ20S Yellow Jacket® Cathode Single Non Power Reducing

Show Larger Photo

Converts your amp to Class A EL84 operation. An adapter that permits the use of an EL84 power tube in place of a 6V6 in cathode-bias amps without dropping the power. There are no adjustments to make and no modifications necessary. You simply plug the Yellow Jacket® into the amp's output tube sockets, screw the ground wires under one of the output tube socket mounting screws, plug the provided EL84s into the Yellow Jacket®, turn on the amp, and play.

Yellow Jacket® converters not only rearrange the pin locations of the tubes, but also provide the necessary current limiting on the screens and cathode as well as blocking the amplifier's grid-bias voltage, configuring the EL84 in a Class-A, self-adjusting cathode-bias circuit.

In Champ- and Deluxe-type amplifiers, the Yellow Jacket® output is smooth, strong and more even than with the stock 6V6s. Any 6V6 using amplifier is instantly converted to a Class A monster with great response and output.
