The Holy Grail of VOX

Your search for the Holy Grail of VOX tone ends here. To commemorate the 50th Anniversary of VOX guitar amplifiers, we are pleased to introduce the first of a new Heritage Collection of hand-wired amplifiers– the AC15H1TV. Rather than just a typical reissue where a vintage amp is dusted off and copied, this amplifier, like the others in the Heritage Collection, transports you through the golden age of VOX tone, combining the prized EF86 preamp channel of 1958 with the 1963 Top Boost channel all in one amplifier. Add in some modern tone shaping control enhancements and the result is perhaps the finest VOX amplifier in the 50 year history of VOX.

The AC15H1TV: A detailed look

The 15-watt AC15 Handwired features two channels of VOX tone through a single 12" Celestion Alnico “Blue” speaker.

Lets breakdown the channels….

Channel 1 is the EF86 Preamp channel, and features two inputs wired in the traditional way that gives them a 6dB gain difference between them. A two-position BASS SHIFT switch is included, with position 1 voiced to the original vintage-correct bass response and position 2 voiced to tighten the bass response and reduce any muddiness during high volume use. The three-position BRILLIANCE SWITCH provides flat response when in the OFF position. Position 1 is a new position voiced like the early AC30 “Treble” amps, while position 2 is the original brilliance circuit, which acts as a dramatic bass cut. The EF86 Mode switch re-configures the EF86 valve from Pentode mode to Triode mode. Triode mode will give a lower gain tone with higher headroom. Pentode mode is the famed original mode and has a very sweet high gain tone with not very much headroom.

Channel 2 is the Top Boost Preamp channel. Like Channel 1, this channel includes two inputs wired with a 6 dB gain difference between them. The Treble and Bass controls are from the 1963 Top Boost circuit and are extremely interactive. Very minor adjustments of these controls can yield dramatic changes in tone color.

And true to VOX form is the Top Cut control, which cuts high from either channel end as it is turned up.

Flexible power

The O/P Switch adds even more flexibility to the AC15. This switch changes the power output valves from Pentode Mode, which is the no
