Wurlitzer sold electronic pianos in bulk to schools from the very beginning. Today, the most common student-model Wurlitzers are the 206 and 206a, which correspond to the 200 and 200a. However, Wurlitzer sold electronic pianos to schools as early as the release of the Wurlitzer 112. Before that, they even sold conventional pianos to schools. Clearly, student pianos were an important part of Wurlitzer’s business model for decades.

The Wurlitzer 206 is the student version of the Wurlitzer 200. It is equivalent to the 200 in every day, but it is mounted on a cabinet instead of legs and some features of the amplifier are disabled. However, all of the components that are in a 200 are also present on the circuit board of the 206. Enabling vibrato and the aux output is therefore as simple as adding some wires and a 10k potentiometer. Here is how we do it.

Carbon composition resistors are those brown cylindrical resistors that you’ll see in most amps made before 1970. All resistors produce Johnson (thermal) noise, a byproduct of the fact that resistors dissipate heat. However, depending in their material composition and shape, resistors may produce other types of noise as well. Carbon composition resistors produce the most noise. But is this really a bad thing? Yes and no.
