TONE, TONE, TONE ?
How the TONE BONE? benefits your amps voice:
The tone of a CLASS A operated guitar amp is well known from the legendary VOX AC30. Tone gets more alive, the amp responds more directly and musically. It instantly improves sustain, thickens tone and is adding a "three-dimensional" character with decent compression and smooth harmonic distortion when driven to the limit. The overall loudness will be reduced as the Class A as the EL84 tubes provides less output volume. So you can crank up your amp all the way and achieve best sonically performance at reasonable volume ( 8 ? 30 Watt, depending on your amp and the TONE BONE? version you use).


PENTODE or TRIODE version?
The TONE BONE? is available as PENTODE and TRIODE version. Both versions basically provide the same benefits. The PENTODE supports the main tonal character of your amp while the TRIODE will clearly make it more linear but will compress and saturate much earlier. The TRIODE makes it sound much smoother and will drop down power output of to about 8 watts when using 2 TONE BONE? converters.
Both versions will provide you outrageous sustain and let you achieve more even distortion sound when cranked up and still give you perfect control with playing dynamics.


PLUG & PLAY or How to install
Switch off your amp, pull out the power tubes (6L6GC, 5881, EL34 or 6V6GT) and plug in TONE BONE? converters including their EL84 tubes, switch amp on. Done!

Size: the ToneBone is without pins 12cm high (5cm adaptor + 7cm EL84).
1cm air gap between the top of the EL84 and Cabinet is required for mounting and air flow.

The TONE BONE? is total self-adjusting. No adjustments, no modifications!
As you do not adjust the bias you might switch back to the original power tubes at any time you want.
Real PLUG & PLAY!


POWER OUTPUT
The overall power output depends on your amp and the version of TONE BONE? converters you use:
Pentode: 7 - 9 Watt per converter, 14 -18 Watt per pair
Triode: 4 - 5 Watt per converter, 8 -10 Watt per pair
example:
A 100-Watt amp with 4 6L6GC, 5881 or EL34 would saturate usually at 100W RMS power output. With TONE BONE? converters it saturates at:
TONE BONE? Pentode: with 4 converters about 32 Watt, with 2 about 16 Watt
TONE BONE? Triode: with 4 converters about 18 Watt, with 2 about 9 Watt

Limitations
The use of TONE BONE? converters is not recommended for amps with Class A / Class AB switching facility (e.g. Fender® Prosonic). These must be used in Class AB position only when using TONE BONEs?.
DO NOT USE the TONE BONE? for amps with cathode controled power amps (e.g. Musicman® RD series, Peavey® Classic 75/100 etc.).
DO NOT USE the TONE BONEs? in Amps with serial filament like the Peavey® Valveking series, Blackstar® Series One
DO NOT USE the TONE BONEs? in Amps with automatic Bias controls like Hughes&Kettner with TSC System
Due to the cathode bias operation of the ToneBone the bias tremolo of the Fender Custom Vibrolux Reverb, Twinolux, Dual Professional and others is out of function
