Rather than list all of the EML101 specifications which are easily available online, I'd like to describe this particular synthesizer. I am the original owner and purchased this instrument in the mid-1970s. I went up to Vernon Connecticut, met Norman Milliard who was one of the owners of EML and picked up my instrument from the factory. I was intrigued with the amount of engineering that went into the construction of this instrument. For example, the way the instrument is constructed, the unit folds into itself to make a carrying case. So much of the engineering and construction was well thought out and was superior to what existed at the time. As a music educator, I used this instrument for demonstrations only. I have retired, and the instrument has been sitting in my house not being used and regrettably I must sell it.

Everything on this instrument is original. It is in working condition but because of its age and lack of use, some refurbishing is going to be required. The following are some examples of what would be required:

The original handle is deteriorating and doesn't feel very secure (this means replace it if you're set on using it. There are some typical rusty spots on the external metal hardware. Three of the original rubber feet are missing. There are some light surface scratches on the outside of the case and a small chip (or two) - check the pics. Several of the Alan – Bradley controls are going to need cleaning. I am sure that some additional internal cleaning on the keyboard will be required but all keys are level and play well / feel fine. These examples should give you some idea of what this instrument might need.

I will include a good amount of literature, too numerous to mention it all.

The owners manual of course is included as well as original patch diagrams sheets. Also included are factory directions such as tuning the oscillators as well as mods that the owner can make. The two mods I made were the addition of a switch to separate the high filter and low filter to create a band reject filter, and a separate external sampler input.

Most important is the inclusion of the schematics for the electronic circuitry. This wasn't easy to obtain, but at the end of EML’s run, thankfully they were willing to give up the schematics to an owner who was truly appreciative of all the work that went into designing this incredible instrument."
