Wurlitzer in the 140 series are transitional models: more reliable than Wurlitzer’s earlier electronic pianos, but not as portable as later models. On the other hand, the 200-series is the iconic final iteration of Wurlitzer keyboards: smaller, lighter, more chrome. If there’s a Wurlitzer 140 (or any of its many variants, from the 140b to the 145) that has caught your eye, you may be wondering if buying it is a good idea. How does it stack up against the 200a? Does it require more work? What are the practical differences between them? This guide is here to help.

If you own vintage gear, you must have a really good outlet to plug it into. There are a lot of options for this, but our favorite is the Furman SS-6B power strip.

Our Furman SS-6B is easily the most essential thing in our studio. Not even exaggerating: it is a pleasure to plug things into this strip. If you have only ever used cheap, flimsy surge strips — or, God forbid, you’ve been plugging all your gear straight into the wall — you are honestly in for a treat when you use this thing. If I could return to any moment in my life, I’d choose the first time I plugged something into my Furman SS-6B, just to relive the surprise and delight of it.

When restoring a Wurlitzer, there are a lot of really tedious and time-consuming steps: polishing keys, lubricating action parts, regulating, tuning, etc. We could go on and on — but we won’t, because today we are talking about rust removal, a task that is not on that list. Removing rust is easy and actually borderline fun because it only requires two things: a little Evapo-Rust and a few hours to kill while the product works its magic.

Some vintage keyboard are in a state of total dilapidation, and will obviously need a lot of work before they can be played. But others are in better condition. They turn on, sound comes out, all or most of the keys work. Is this enough? When can servicing a keyboard that “works” make it perform much better?

The most common sustain problem on a Wurlitzer 200a (or earlier) keyboard is too much sustain: the note continues to ring out, even when the pedal is not depressed. This is almost always caused by damper felts that are excessively compressed or otherwise deteriorated. In other cases, the Wurlitzer’s sustain pedal doesn’t do anything when depressed, and the piano never has sustain. This is usually because the pedal is not making the proper interior connection. This guide will help you address both problems.

There was a time when vacuum tubes were a huge industry. Just about every time of consumer electronics required tubes, and manufacturers competed for a slice of the pie by offering greater resiliency, lower noise, longer lifespans, etc. And then cheap silicon transistors were invented.

We have a soft spot for the 200, because it was our first Wurlitzer electronic piano. Our favorite Wurlitzer model changes from minute to minute, but the 200 always has a strong case. It’s the final iteration, sleek and stripped-down - not an inch of wasted space - with features that have been arguably perfected from the previous versions. Electronically, though, it’s still ancient technology. It’s rough around the edges. The 200a was a necessary upgrade - but that doesn’t mean that we have to like it better.

This Dynavox was originally a so-called widowmaker amplifier. We completely rebuilt it with all-new components, installed a power transformer, and revised the circuit to eliminate the obsolete widowmaker tubes. It is now a safe, functional 1.5 watt practice amplifier. It can be used alone for bedroom practice, or plugged into a second amp for interesting tube overdrive tones.

Here’s some details on how we redesigned this amp.

A widowmaker amplifier has no power transformer or fuse. Instead, the two-prong, non-polar power cord is wired directly to the rectifier tube. It is very unsafe, because under even minor failure conditions (such as a shorted capacitor or even - in some models - plugging the power cord in backwards), the mains voltage might end up on the guitar strings and the user will be shocked/electrocuted.

On the plus(?) side, power transformers are expensive so widowmaker amps could be manufactured and sold at a lower price. This ensured that every aspiring guitarist in America could own a low-fi death trap if that’s what they really wanted.

We are extra-excited about this group of four Wurlitzer 200 student pianos because they are clearly of an early manufacture. Three of them had original music racks with the closely-spaced metal bars, which are incredibly rare. Even aside from that great detail, however, all of the keyboards were in great shape. They had clearly been used only lightly and had been stored in a clean, low-humidity area.

We drove through the eastern U.S. on a pickup/delivery run last week. (Little-known fact! We do deliver long-distance. More info here.) We dropped off our gorgeous Wurlitzer 720a, and then picked up a handful of new pieces: a teacher/student 206a/207a pair, a 203w wheeled console Wurlitzer, an extremely rare Wurlitzer 140a, and a Fender Rhodes Mk I.
