The documents include engineering drawings for Wurlitzer electronic pianos, electronic organs, combo organs, drum machines, tone cabinets, and other instruments manufactured in the Corinth, MS, factory. Wurlitzer jukeboxes, theater organs, and band instruments were manufactured at different factories, so unfortunately we don’t have any of those drawings.

Wurlitzer assigned a part number to every component in the keyboard. Sometimes components are grouped together in an assembly, which also has a part number. So, for instance, an amplifier would have a part number, and then the parts of the amp such as the PCB, the PCB traces, the transistors, etc., would all have separate part numbers.

The vast majority of part numbers are six digits. Some earlier part numbers, for instruments manufactured in the 1950s or early 1960s, have five digits.

Sometimes, the part number is printed on the part itself. Sometimes, you can find it in the service manual. We have a partial collection of bills of materials, which list the part numbers of every part in the keyboard/instrument, but we haven’t scanned them yet.

If you can’t find the part number, no problem. Just include a description of the part. As we scan, we’re building a list of part numbers, models, and other info that we can cross-reference, so that we can find documents by type and instrument as well as by part number.

Unfortunately, the unscanned documents are not organized. So, we are only able to look for documents once they are scanned. For that reason, we can’t give a timeline for when we might find the document. But we are scanning new documents every day, and we will let you know as soon as we see your part number.

Donating helps us scan faster! The biggest bottleneck is storing the documents that we have scanned. Physical storage (folders and storage space) and digital storage are big expenses. Even a $12 donation (the cost of a box of folders) is a huge help! We have 100,000 documents and we need thousands of folders to safely store them.

If you can’t donate, please consider sharing this website or telling a friend. The main goal is to get the documents to people who can use them to repair keyboards, make new parts, and—ultimately—use this cool analog technology to make music. The fact that people want to see the documents makes us want to keep scanning them!
