Welcome to Granger Amplification. We manufacture high performance vacuum tube amplifiers.



Granger H50 Legacy valve amplifier

The Granger H50 "Legacy" valve amplifier is a tribute to, and inspired by the late 60's Dave Reeves (of Hiwatt fame) amps made famous by bands like The Who, Pink Floyd, and Led Zeppelin. Big and loud rock tone, that goes from super clean to super crunchy. This is a great medium-to-large-venue gigging amp, i.e. it gets very loud! There are interactive Pre and Post Master Volume controls, as well as Volume controls for the Normal and Lead channels, so the tonal combinations are many. There are no footswitches or relays - just pure all-tube tone using the finest tone-enhancing components. All internal components are hand selected for both their tonal characteristics and durability. Metal film, carbon composition, and carbon film resistors are all strategically used throughout the amp. The preamp consists of 4 ECC83S valves and power is solid-state rectified (diodes). The power section runs on two KT66 which produces well over 50 watts when fully overdriven into saturation. EL34, 6CA7 or KT77 can also be used. For the service-minded player, an external bias adjustment pot with low voltage test points allows the user to set bias when replacing output valves without removing the chassis.
