Tube Converter - Yellow Jackets®, YJ7591
The YJ7591 is a specialized, current-limiting/voltage-conditioning adapter for use in most amplifiers that use 7591 output tubes. Only the triode version will provide a noticeable power reduction. The ground wire connects to chassis-ground for cathode-biased amplifiers. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJ20, Triode version
The YJ20 is for use in most amplifiers using 6V6 output tubes. The YJ20 is similar to the YJC but does not drop the plate and screen voltages. It is meant for use in lower power output amps (20 watts or less) when no power reduction is desired. The ground wire connects to the chassis-ground for cathode-biased amplifiers. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJC, Triode version
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. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.
