Brian’s List: Wurlitzer Woes

BRIAN’S LIST: SHOWCASING THE BEST DEALS AND INTERESTING FINDS IN MUSICAL EQUIPMENT IN NEW YORK CITY.

Deeply apologize folks for missing last weeks installment! I was knee deep in repairing my Wurlitzer 140B, a beautiful electric piano from the mid-sixties. The Wurlitzer company made many instruments, recording devices, and electronics over the years but the one thing that everyone thinks of when they hear Wurlitzer is their electric pianos. These mechanical pianos function much like a real piano with spring weighted keys that respond to pressure that swing felt hammer tips up and hit the reeds thus generating the notes. The sound is then amplified by the built in power amp and send out to (in most models) built in speaker(s) for nice quiet home use and jams. There is a line-out as well so you can go into an amp for added power for full band work. Also, features a headphone jack for late night playing!

The most commonly found Wurlitzer is the 200A model; made from around 1967 to 1982.

They are solid state, feature a plastic lid (140 series prior to this had a metal lid with wood frame) and lighter more compact design then previous models. The famous feature we all have heard on the records we love is the vibrato effect they produce.

Better to just listen then me explain this classic sound:

There are 64 keys on these pianos and hundreds of moving parts that are made out of wood and felt. These wear down after years of use and need to be changed out to avoid sluggish action, dead keys and insure a consistent feel and sound across the piano. I took on the task of opening my Wurlitzer up and lubricating all action parts, replacing the spring in each part, along with a few felts for good measure. This was very tedious but Vintage Vibe in NJ sell new springs, a special lubricating solution along with helpful videos on youtube and others for download that can guide you threw the process – too some extent. Gotta have the patience, time and space for this kind of job.

Here you can see my 140B with the lid off, damper rail and reed bar removed. Step one is too vacuum inside this guy to remove any dust, hair, dirt and cheese doodles that slipped their way in over the years. Dust can get on the reed bar and cause static and crackle as it gets in the way of the signal.

Next I removed all the action keys on the right side and began the process of removing all the springs.

These little guys are 50 years old at this point. One snapped on me which kickstarted this repair. It’s very easy to see and feel once we are up this close how weak and brittle these springs are. Multiple applications of acetone later you can slowly scrap the old glue out, remove the spring and glue the new spring in place.

At this point I replaced all the springs on the right side of the piano and am almost done with the left. The action parts are laid out and glue is drying.

Once I put them all back in place I began the painful process of putting this machine back together. Be prepared for many snags along the way as things need to be adjusted every so slightly to make sure everything is working and fitting back in place properly.
