Vacuum Tube Accessories

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.
P-YJC-T Tube Converter - Yellow Jacket®, 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 Jacket® converters come with JJ Brand EL84/6BQ5 vacuum tubes.
  • All Yellow Jacket® converters come with JJ Brand EL84/6BQ5 vacuum tubes.
  • Converts most audio amplifiers with 6L6s, EL34s, 6550s, or 6V6s and similar-based tubes to EL84s without modification or rebiasing.
  • Converts: Class AB to Class A operation
  • Drops Output Power: 70% to 90%.
  • Safe for all common amplifiers and transformers.

Yellow Jacket® converters are a type of specialized adapter which permit the use of EL84/6BQ5 power tubes in place of 6V6, 6L6, EL34, and 7591 type vacuum tubes.
