The YJUni is a simple pin-converting adapter for use in most amps with 6V6 or similar based tubes like 6F6, 6G6, 6K6, 6Y6, etc. The YJUni is shorter than standard Yellow Jacket®. It is designed for use in lower power output amps (20 watts or less) when no power reduction is desired. If your amp is cathode-biased, then no bias adjustment is needed. If your amp is fixed biased, then the bias should be adjusted just as it would be according to the standard biasing instructions included with the amp.

The YJC is similar to the YJS, but for use in amps with cathode-biased power tubes. Cathode-biased power tubes have a bias resistor connected from their cathode to ground. The ground wire of the YJC is used to bypass the amp’s cathode bias components so the Yellow Jacket® converter’s internal bias components are used instead.

This Yellow Jacket converter is a specialized adapter which permits the use of EL84/6BQ5 power tubes in place of 7591A 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 Jacket 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.
