Over the years we have seen VHT amplifiers in for repair, mainly the pitbulls. On almost all the VHT amps we have repaired we also upgraded them with the Tubesync technology to provide active bias control and valve overload protection.
Not all broken VHT amps are expensive to repair and the typical daily wear and tear items are straight forward to repair and include.
Replacing capacitors causing hum
repairing intermittent problems with amp breaking down
Re valving and biasing
Foot pedal repairs
