VOX HERITAGE AC15HTVH 15W HEAD

Make no mistake, the AC15HTVH is no dizzy blonde. Inside that pretty head is a hand-wired masterpiece of tone that can transport you through the golden age of Vox tone. It combines the prized EF86 preamp channel of 1958 with the legendary 1963 Top Boost channel in one masterfully designed amplifier. With its modern tone-shaping control enhancements, you've got one of the finest Vox amplifiers in the company's 50-year history.

The EF86
The magical Vox tone. But what is it that makes EF86 based Vox amplifiers some of the most collectible in the world? Maybe it's the way the amp naturally overdrives, almost breathing with a life of its own. Perhaps it's the transparency of tone that flatters a premium quality guitar, or the way it dynamically responds to the subtlety of your picking. Or maybe it's the raw power of the creamy distortion as you crank the amp all the way up. Whatever it is, there is an undeniable magic about this period of Vox amplification--an age when the most simple of circuits produced some of the most complex and musical of tones. Now in short supply, the EF86 Pentode tube is at the heart of this elusive tone. Fifty years later, the magic returns.

The AC15H Head
A detailed look. The 15-watt AC15 hand-wired head features two channels of unmistakable Vox tone. The valve complement is made up of 1 x EF86, 3 x ECC83/12AX7, 2 x EL84, and 1 x EZ81 (rectifier).

Channel 1 is the EF86 Preamp channel, and features two inputs wired in the traditional way providing 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 less headroom.

Channel 2 is the Top Boost Preamp channel. Like Channel 1, this channel includes two inputs wired with a 6dB 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's 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 normal operating mode of the power amplifier, to Triode Mode that halves the power output to 7.5 watts and at the same time offering smoother tonal characteristics.

The finishing touches
Great care and research went into the cosmetics for this special amplifier that perfectly blends authentic vintage styling with contemporary attributes. These touches include vintage "TV Front" cabinetry, pre-1960 logo placement, and vintage-inspired cream vinyl covering.
