For Sale…. THD UniValve Box-Head Amp

This Head Box is fitted with a THD UniValve 15 Watt Class A amplifier head with a single output tube that can be switched at will among many octalbased power tubes for different tones without re-biasing the amp. Useable tubes include 6L6, EL34, 6550, KT90, KT88, KT77 and KT66 – easily accessible and interchangeable from the rear of the combo cab.

With the amp in “LoV” setting you can use 6V6 for a total output of 5 watts. A special UniValve Yellow Jacket™ Converter is available allowing the UniValve to use the popular EL84 power tube at a total of 4 watts output power, also in “LoV” setting.

Likewise, the two preamp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7 or 12AZ7.

It has a built-in Hot Plate™ Power Attenuator that allows for full output distortion at almost any volume.

The UniValve delivers tones from smooth and clear to very aggressive overdrive. It is easily capable of driving a 4 x 12 cabinet, yet equally at home in THD’s 1×12″ Combo Cab. CEO Andy Marshall minces no words. “It’s one of the best sounding cabinets I’ve ever heard,” he said “It’s every bit as full and tight as our 2×12″ cabinet, but smaller and it records beautifully.”

Full 15 Watts power is available to all speaker selection modes, from 4 to 16 Ohm

Available only in Black.
