The signal path for gain, EQ, contour and the DI are 100% tube driven, achieving classic tube performance with 300V plates.

Inherited from the 800RB, this unique tube design varies the EQ bandwidth to retain a musical response even at extreme settings.

Switch mode power amp and supply deliver a crushing 500 Watts of cool running power.

Temperature controlled fans keep the amplifier cool delivering only the required amount of air, reducing noise and dust intake.

Thoughtful handle design protects the front panel controls.  Internal sensing circuitry will indicate problems on the power switch ring. Blue is good!
