The YJS is a specialized, current-limiting/voltage-conditioning adapter for use in most 20 to 100 watt amps that use 6L6, EL34, 6550 or 6V6 output tubes. The YJS is for amps with fixed bias power tubes. (Fixed bias tubes have their cathode connected directly to ground and a negative DC voltage applied to their control grid). All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

The YJShort is shorter than the standard YJS converter, allowing for use in amps that do not have room for the standard converters. It is a specialized, current-limiting/voltage-conditioning adapter for use in most 20 to 100 watt amps which use 6L6, EL34, 6550 or 6V6 output tubes. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

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 Jackets®. It is designed for use in lower power output amps (20 watts or less) when no power reduction is desired.

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.

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.

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.
