For sale Genz Benz Streamliner 900

These are great amps.

If I used my amp more (mostly DI/IEM these days) I’d be all over this. A Jeff and Andy tube amp. Well, tube preamp anyway.

Indeed, really an amazing amp. There's plenty of TB threads about the Streamliners, but in case someone
is looking for more details about the product, here's some stuff I had saved from GB "back in the day":

"The Streamliner STM-900 bass amp head from Genz Benz boasts a 300-volt, all-tube Class A preamp driven by three 12AX7 preamp tubes utilizing six gain stages. The STM-900's preamp design features an intuitive and highly effective tone network which is a unique blend of a modified passive Baxandall network for the bass and treble along with an active, tube-driven mid filter with selectable mid frequencies. The versatile all-tube preamp exudes a fat and rich tone that remains articulate. It can be used to simply add warmth to your natural tone or it can be dialed in to provide a wide range of natural tube overdrive.

The Streamliner 900 also features proprietary 3 Dimensional Power Management analog technology that adds heft and girth to each individual note while enhancing the amplifier's responsiveness and headroom. It provides the dynamic and three-dimensional tone and feel of an all-tube power amp design.

With its solid extruded aluminum panels, CNC machined solid billet aluminum faceplate and smooth-radius edges the Streamliner 900 chassis emanates the ruggedness and strength of a world-class touring machine. This brushed aluminum chassis is finished in an anodized Tungsten finish.

The powerhouse behind the Streamliner 900 is a Class D amplifier and SMPS module, enhanced with patent-pending P.H.A.T. (Proprietary Heat Abatement Technology) topology. This delivers robust and reliable, high output performance in a tremendously compact and convenient package.

Simply put, the new design of the STM-900 offers a more streamlined approach to finding your voice, yet it still carries forth the GENZ BENZ reputation for performance, reliability, and innovation.

I sent mine to @agedhorse for a tune up. It came back louder and with much punchier tone. He does great work. I also had the fan replaced and the LEDs fixed. His servicing was worth every penny. It makes these into much better amps. This one is also priced well. Someone should grab this. I already have 2.

My favorite amp. The headphone out is amazing as well. Truly glorious sounding with some nice cans. GLWTS

Great amp!

All time fav amp!

I would have been tempted to add a 3rd 900 to my collection. Someone will be very pleased!
