THD BiValve-30

In s tructio n Manua l

Thank you for your purchase of the THD BiValve-30 amplifier! The big brother of the

THD UniValve, the BiValve-30 is a Single-Ended Class-A amplifier head with dual

output tubes that can be switched at will among many octal-based power tubes, including

6L6, EL-34, 6550, 6CA7. 6V6, 6K6, KT-90, KT-88, KT-77 and KT-66, for different

tones without re-biasing the amp. The two output tubes do not need to be matched in any

way—you are free to experiment with any combination you want! Likewise, the two

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

BiValve-30 delivers tones from smooth and clear to very aggressive overdrive, like the

UniValve, but with more power and a much more compliant output transformer for

thicker lows. It is easily capable of driving a 4x12" cabinet, yet quite small and relatively

light. Finally, it has a built-in Hot Plate® Power Attenuator that allows for full output

distortion at almost any volume. The unique combination of our touch-sensitive input

circuit and the wonderfully active and reactive tone control section (that we slaved a year

to perfect) make for a front-end that really responds to subtle and not-so-subtle changes

in the signal being fed into the amplifier either by the guitar or any effect that may be

between the guitar and the amplifier.
