INTRODUCTION
Congratulations on parting with your hard earned cash, and getting yourself the future classic, AC4TVH!
Even though, historically, VOX has produced an AC4 (a 4 Watt, Single-Ended Amplifier), it was decided
that a mere re-issue was not going to be enough. The original AC4 used the EF86 Preamp Pentode tube
and an EL84 Power Pentode tube. This tube complement was fine for the 1950s guitarist, as there was
no cascading preamp gain stage. This meant the amplifier would not overdrive well. It was decided this
would not be suitable for the modern day guitarist, as we like to have the option of having clean, crunch
or wonderfully saturated overdrive.
From this, the AC4TVH was born!
Cosmetically inspired by the VOX AC15HTVH (part of the Heritage Collection), the amplifier features a
Tone control, Volume (Gain) Control and an Output Level Attenuator. This means you can have all the
great overdrive you need at more “neighbour friendly” levels!
Enjoy!

FRONT PANEL LAYOUT
1. INPUT Jack - Insert Guitar Here!
2. TONE Control - Used to control how bright or dark the overall sound of the amplifier is.
Fully counter-clockwise is darker and fully clockwise is brighter.
3. VOLUME Control - Controls (you guessed it!) the volume of the amplifier. For a cleaner
sound, the knob should be set anywhere before 12 o’clock and for a more aggressive,
overdrive sound... why not crank it!
4. OP LEVEL (Output Level) Control - This control has 3 positions:
a. 4W - This is full output level of 4 watts.
b. 1W - This is 1 watt output level.
c. 1/4W - This is 1/4 watt output level.
An attenuator is used to achieve this, meaning you can crank it to get the saturated overdrive
you require......but keep up neighbour relations, by keeping the relative output level low.
5. Power Switch - Used to power up!
6. Indicator - Used to see power up!
