Adapters - Tube adapters have many applications; allowing use of less expensive tube types, changing the tone of your amp or for use as a socket saver.
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 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.
Converter-only version of the P-YJC. Tubes not included. Requires an EL84 vacuum tube, such as:
T-EL84-EH (Electro-Harmonix)
T-EL84-GEN (Genalex)
T-EL84-JJ (JJ Electronic)
T-EL84-MUL (Mullard)
T-EL84-MP-PV (Peavey)
T-EL84-S-MP-GT (Groove Tubes)
T-EL84-SOVT (Sovtek)
T-EL84-TAD (Tube Amp Doctor)
T-EL84-TUNG (Tung-Sol)
T-EL84_6BQ5 (NOS)
T-EL844-JJ (JJ Electronic EL844)
T-EL84M-SOVT (Sovtek EL84M)
We also sell an EL84 sampler set containing 9 EL84 tubes:
T-EL84-SET

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.
