Tube Converter - Yellow Jacket®, YJ7591
Package of 2
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 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 7591s and similar-based tubes to EL84s without modification or rebiasing.
  • Converts: Class AB to Class A operation
  • Drops Output Power: Slightly.
  • 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.

Tube Converter - Yellow Jacket®, YJ7591, Converter Only
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.
