Tone bones and Yellow Jackets are converters which allows replacement of 6L6GC,6V6 GT 5881 & EL34 with EL84 valves.
Converters were first brought to public attention by Andy Marshall of THD with his yellow jackets with the aim of allowing the musician to reduce the volume of their amplifiers. Amplifiers which operate in Class A mode such as the VOX AC30 have a sonically richer and more responsive tone. Converters allow you to recreate part of this tone with your amp. They also provide a significant drop in volume of between 8 to 30 watts depending on your amp and the tone bone used.Tone bones are ideal for recording, home practice or for small gigs. Two versions of the tone bone are available with either Pentode ot Triode operation.

TRIODE OPERATION
The character of your amp will change. In Triode operation your amp will have more compression / sag. The amp will become more touch sensitive with the output stage distorting a lot sooner.
The greatest volume drop will be gained by using the Triode tone bone. In a 100 watt amplifier 4 triode converters will produce around 18 watts. In a 50 watt amplifier they will produce around 9 watts.
Dimension of the Tone bone overall height
measured from the base of the tone bone 12cm high (5cm adaptor + 7cm EL84).
You need to allow a gap at the top of the EL84 in the cabinet for air flow.
Tone bones are supplied in pairs and come with two TAD EL84 STR output valves
