Organ service manuals
Wurlitzer Organ Service Manual, 4100 Series
This service manual contains detailed explanations of organ functionality, schematics, and extremely stylish diagrams. (We love the exploded diagram of the chord unit.) It also has many schematics relating to the 4100, 4102, 4150, and suffix variants such as the 4100BD. Many schematics include multiple circuit revisions, so this is a great manual for anyone who is repairing a 4100-series organ or who is interested how classic tube circuits were modified over time.
Stereo service manuals
Wurlitzer Solid State Stereo MC-1 MS-1 Series 100 credenza
This is a really cool vintage stereo—look up some photos to check it out! The MC-1 is the record player portion. It has a radio tuner, and the top rolls up like a garage door to expose the turntable underneath. The MS-1 refers to the speakers. The service manual has schematics, a dial stringing diagram, and AM and FM alignment procedures. It also includes a layout diagram of the MC-1 that labels all of the internal parts—helpful for repair, even if the birds-eye drawing doesn’t fully depict how cool this stereo’s external design is.
Tone cabinet manuals
Wurlitzer Auxiliary Amplifier Model 920
Instructions for Setting Up and Operating
This manual includes photos and diagrams of the Model 920, and explains how to connect it to a Wurlitzer 112 or 120. This is a very interesting read. The 120 does not have any preamp outputs, so the 920 connects to the fully-amplified headphone out. That’s a lot of gain since both the 120 and the 920 have push-pull 6V6 output stages, and the piano input is placed correspondingly late in the circuit. However, the 920 also has a more traditional (unbalanced) microphone and instrument input, which connect to different points earlier in the preamp. In sum, the 920 has three different inputs providing three different levels of tube-powered gain. This is probably a very fun amplifier if you are lucky to find one!
