Tube Converter - Yellow Jackets®, YJ20

Starting at: $44.95
In stock

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.

  • All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.
  • Converts most audio amplifiers with 6V6s and similar-based tubes to EL84s without modification or rebiasing.
  • Converts: Class AB to Class A operation
  • Drops Output Power: Does not drop power.
  • Safe for all common amplifiers and transformers.

Yellow Jackets® 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. Yellow Jackets® converters allow you to harness the musicality of EL84 vacuum tubes in amps that don't use them already - it's like getting a whole new amplifier!

There is no rebiasing involved, which makes modifying your amp's tone very easy. Yellow Jackets® converters give you simple Class-A operation from any amp. They not only rearrange the pin locations of the tubes, but also provide the necessary plate voltage drop and current limiting on the screens as well as blocking the amplifier's grid bias voltage while configuring the EL84 in a Class-A, self-adjusting cathode-bias circuit. In other words, there are no adjustments to make and no modifications necessary, you simply plug the Yellow Jackets® into the amp's output tube sockets, (in cathode-bias amplifiers) screw the ground wires under one of the output tube socket mounting screws, plug the provided EL84s into the Yellow Jackets® converters, turn on the amp and play.

All Yellow Jackets® have a one year warranty against manufactured defects.
