EML Prototype?



via this auction

Details:

"To my knowledge, this is a unique synth. It appears to be an EML prototype. Basic features are - 2 VCOs, multi-mode filter, VCA, AR envelope, sample and hold, and spring reverb.

Given the professional build of the case, the use of some pre-made circuit boards and some breadboards, and the overall sound, it appears to have either been made by EML or made by someone closely associated with EML. I don't have any specific documentation on this synth, but I do have some tech sheets and circuits that seem to closely resemble most of what's in here.

Some paths are pre-patched, and I am including 10 patchcords to make additional connections. I've tested most of the functions, knobs, and jacks and so far, the only thing I need to look at is the LFO LED is not blinking.

The raw oscillators and the multimode filter sound great and the spring reverb is an Accutronics and definitely high quality.

As you can see from the pictures, the VCF board is labelled EML VCF and the VCA board says EML-100 along the edge. Most of the boards have hand-written dates of 1977 on them, so that gives a good idea of when this was assembled.

So, now you know what I know about this. It's a 110v power supply. I didn't see an obvious way to switch it, but it looks like the same power supply as used inside the EML 101, EML 200 and EML 400."

  2. I think this is more likely a synth built from the PCBs EML sold when they were going out of business.

  4. EML lasted until the early 80s. Most likely an employees side project...

  5. This blog and Drama Prairie Dog are the main reasons why the internet is great.

  6. i have a friend with music easel which as some EML circuits built into the case around the Buchla 208 module. he bought them around the time that EML was going out of business. however, the graphics on these boxes don't match the graphics of the synth in question, or any actual EMLs i've seen. i agree, someone who worked there's side project. or prototype. or somthing else entirely. the plot thickens.

  9. I missed the Notron. Just put it up. Dave, that prairie dog thing was hilarious. Had to watch it several times. If it was only sitting on a synth...
