On the Wurlitzer 112 service manual
We have a lot of affection for this 112 service manual. First of all, the manual’s Introduction conveys a lot of the excitement surrounding the electronic piano, now available in the new-and-improved 112a version. It is an “entirely new concept!” It is “similar in many ways to the conventional piano” and yet “quite different!” It is a “piano with a purpose!!”
Why We Love Wurlitzers with Built-In Leg Storage
Early Wurlitzer keyboards — the 112, 120, and 140-series — have built in leg storage. The outer lid (which is hopefully still present all these years!) has a space to firmly screw in the legs, as well as a little strap in the center to hold them in place. This is probably early Wurlitzers’ most underrated feature!
Why does my Wurlitzer 112 amp have a weird octal plug that goes nowhere?
The Wurlitzer 112 has a mysterious octal plug that appears to go nowhere. It is very similar to the wiring harness plug, except that it doesn’t end in a wire. It’s just a little black dome that occupies chassis real estate and doesn’t appear to do anything in particular.
On reading Wurlitzer patents
What is a patent? A patent is a form of compromise. When you patent an invention, you must describe it in detail: specifically, enough detail that someone with a background in your industry would understand how to recreate your invention just by reading the patent application. In return for this valuable information, you are given the exclusive legal right to make and sell your product for a certain number of years. If someone else makes or sells your product during the time period covered by your patent, you have the power to sue them for patent infringement.
Drawing the Line Between Troubleshooting an Amp and Modifying It
When you repair an amplifier, you have two choices. You can bring it back to its original state by fixing only what is broken. Or, you can improve the circuit by modding it.
There is a lot to love about an amplifier that is in fully-functioning, but original, condition. When using a vintage amp, you are playing music on a slice of time. You are combining two different musical periods in a way that is impossible to replicate with any other gear. It’s basically time travel.
How Many Wurlitzers Should I Have?
This may sound crazy, but if you can’t decide which model of Wurlitzer is right for you, you may need two Wurlitzers. All Wurlitzer models have subtle differences between them, from the amp to the reeds to the feel of the keyboard. In some respects, these differences can make two Wurlitzers of different models sound like two totally different instruments. In order to achieve all of the tonal possibly a Wurlitzer can offer, you may need two Wurlitzers.
