a Duet Set comprising two THD Yellow Jacket tube adaptors AND two EL84 power tubes – in the original THD packaging.
Yes – completely new and unused.
THD Yellow Jackets are specialized adapters which permit the use
of EL84/6BQ5 power tubes in place of 6V6, 6L6, EL34, 7027 6550
(under 520 volts) and 7591 types. They will work in any amplifier that takes these tube types, as long as the plate voltage is under 520 VDC.
This accounts for over 98% of the tube guitar amplifiers on the market. (They also work in tube Hi-Fi equipment!)
Because the Yellow Jackets ignore the amplifier’s grid bias voltage, it is possible to take them in and out at will to adjust your power level and sound for the individual gig or session.
Typical results of installing the THD Yellow Jackets/EL84s….
“The treble response was enhanced, the midrange somewhat thicker, and the amp produced rich, glassy distortion and sparkling clean tones similar to those of a Vox AC30.”
So “What do you do if you’re tired of the way your amp sounds, but don’t have the bucks to buy a new one or to have some high-priced amp surgeon modify its innards?”
