Wurlitzer 200 and 200a keyboards came with some essential accessories and parts, as well as some that were optional at the original time of purchase. If you are less familiar with a Wurlitzer 200 series keyboard, you might overlook something that is critical and you’ll want to have. For the sake of this article, we will be discussing exterior items and accessories, not internal mechanicals, and will be focusing on the 200 and 200a. However, a lot of this information can be applied to the rest of the 200 series (such as 203, 210, 214, 206 and so on).

In Part I of our guide on fixing hum, we listed some easy fixes. In Part II, we’ll go into further detail on techniques that require some prior electronics experience to execute. It’s worth checking out Part I first, because it listed some simple, non-invasive things that you should always be tried before diving into the amplifier’s circuitry. For the purposes of this article, we’ll assume that you already tried everything in Part I. This includes:

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

But before we talk about that, let’s back up a little. The Wurlitzer itself is very analogous to an electric guitar: the heart of both instruments is a pickup that converts vibration into an electrical signal that is ultimately sent to an amplifier. In a guitar, the amplifier is almost always external, but a Wurlitzer’s amplifier is tucked into the body of the instrument.
