On the Wurlitzer 120/700 Amplifier

This vintage tube amp was removed from a Wurlitzer 700 electronic piano. It’s is the same amplifier as a Wurlitzer 120…unfortunately. The 120 had very limited cabinet space, so that’s why the physical design of the amp is so cramped. On the other hand, the 700 had a cavernous cabinet that could definitely have handled a larger amp chassis. Oh well: that ship has obviously sailed.

Wurlitzer 120/700 Amplifier: Circuit Analysis

The Wurlitzer 120 amplifier represented a total redesign from the previous Wurlitzer model, the 112. The upside is that the amp is a lot smaller, so it fits nicely in the smaller, lighter 120 cabinet. The downside is also that the amp is a lot smaller. It’s missing many of the features that make the Wurlitzer 112 so magical. Regardless, it’s still a great vintage tube amp with a lovely, classic tone.

How is a Wurlitzer tube amp different from a guitar amp?

Wurlitzer tube amps are in fact very similar to guitar amps.

In a guitar, the amplifier is almost always external, but a Wurlitzer’s amplifier is tucked into the body of the instrument.

This Wurlitzer 120 arrived in exceptional condition. It had spent many years studio, a carpeted, finished basement housing an enormous collection of jazz records. Really the only indication that this keyboard is a late-50s vintage is the splatter-paint finish. It doesn’t show any of the cosmetic wear that you’d expect from a 60-year-old piece of gear. There’s a little bit of dust in the cheek block tolex, a little bit of patina on the metal parts, and that’s it.
