Wurlitzer 140b
The 140b is at the midpoint of Wurlitzer's electronic piano production: a stepping stone from the vintage tone of the 100-series to the more reliable modern electronics of the 200-series. The mechanical parts are easier to work with. It has updated, 200-style reeds. It has a transistor amplifier like the 200, but an early one, with germanium power transistors and neon bulb vibrato.
