What is the Difference Between a Wurlitzer 140 and a Wurlitzer 200a or 200?

Wurlitzer in the 140 series are transitional models: more reliable than Wurlitzer’s earlier electronic pianos, but not as portable as later models. On the other hand, the 200-series is the iconic final iteration of Wurlitzer keyboards: smaller, lighter, more chrome. If there’s a Wurlitzer 140 (or any of its many variants, from the 140b to the 145) that has caught your eye, you may be wondering if buying it is a good idea. How does it stack up against the 200a? Does it require more work? What are the practical differences between them? This guide is here to help.
