Thanks to EMS Industrial for constructing the control panel for the organ. Although quite unnecessary, it will sure be neat to watch the meters dance around when the organ fires up and plays! The panel offers readings on logic rectifier voltage, magnet rectifier volts and amps, blower 1, 2 and vacuum pump wind and controls for the frequency drives that power the blowers. In addition to those functions, you can manually start the blowers individually as well as the rectifiers and vacuum pump. The instrument will normally be controlled by a single switch next to the relay counter upstairs.... but that is boring in nature so thus this panel!

After starting this project several months ago, it is finally finished thanks to the new primary box gaskets that were punched at Jeff Weiler's shop.

First off, thanks to my friend Gary Bieck for giving me this Wurlitzer Shuffle. Second, to answer the question of what is a Wurlitzer Shuffle. To explain, I'll describe what a Wurlitzer Surf is first. A surf is a box that is typically attached to a wind trunk, operating on static pressure. This box has a pneumatic inside that slides a piece of wood back and forth, allowing wind to escape from the box through a slit in the top. In-line with the slit is a piece of sheet metal that the wind passes over as it rushes out. The large pneumatic inside has a "bleed" screw that controls the rate it moves. The end effect sounds similar to the surf rolling in and out. Now that you understand a surf, apply the exact same concept (and design) to the shuffle, with the addition of a primary box that allows the large pneumatic inside to move quickly. This makes it possible to play the shuffle rhythmically. This particular shuffle got hit with water at some point during its life. Therefore, wood glue and lots of clamps were deployed during the restoration of this unit.
