Has anyone done this and is it OK? They are the THD Yellowjackets YJSD model and I can't find much info on the VOS (45 watt with EL34's) and whether it's got less than 520 plate volts. I guess I could get out my DMM and check but I don't wanna take the amp apart tonight.
Here is some info on the model of YellowJacket, I thought there was only one version but there are like 15.. Thanks all.
Yellow Jackets plug into the power tube socket of your amp and replace the power tube you are using with an EL84. They turn "Class AB" amps into a "Class A" circuit, and can be used as long as the plate voltage is under 520 volts. As THD says, this covers 98% of guitar amps in use. They can also be used in home audio equipment.
The "YJS" model of Yellow Jacket also reduces the amplifier's power by 50% to 70%. They can be used to replace 6V6, EL34, 6L6 and 6550 tube types without modification or rebiasing. In amps with four power tubes, you can replace two of the tubes with Yellow Jackets for a partial power reduction. The EL84 tubes are included.
