ADAPTER, YELLOW JACKET, CONVERTS 6L6, EL34 TO EL84/6BQ5
This Yellow Jacket converter is a specialized adapter which permits the use of EL84/6BQ5 power tubes in place of 6L6 or EL34 type tubes. Yellow Jacket converters not only re-arrange the pin locations of the tubes but also provide the necessary current limiting on the screens and cathode. Yellow Jackets' block the amplifier's grid bias voltage, which configures the EL84/6BQ5 into a class A self adjusting bias circuit. Tubes are not included. Manufacturer recommends the JJ EL84/6BQ5.
