VHT Special 12/20 Tube Set
The VHT Special 12/20 Tube Set consists of 3 x 12AX7 preamp tubes and 2 x 6V6 power tubes.
Building on the success of the popular VHT Special 6 and Special 6 Ultra, the VHT Special 12/20 features increased power (with two power ranges), a unique preamp specifically designed to excel with pedals and multi-effects units, a convenient built-in 9-volt DC pedal power supply, an all-tube buffered effects loop with send and return level controls, VHT’s unique Depth and Texture controls, and variable Watts control.
To optimize the amp for a wide range of output tubes, the VHT Special 12/20 offers two output-power ranges; safely located behind the rear panel, a special voltage range switch provides the proper voltages for 6V6 or EL84 output tubes (in 12-watt low-voltage/low-power mode). The high voltage 20-watt setting provides the ideal voltages for higher-power 6L6 or EL34 output tubes. The Special 12/20 ships from the factory with a pair of 6V6 output tubes (VHT 6V6-to-EL84 socket adapters are required for operation with EL84 tubes). In addition, the Special 12/20’s variable Watts control can reduce the maximum output power to less than one watt for whisper-quiet volume levels.
