To my best recalections, the none of the EML synths had any sort of DC power output jacks. Would have been nice though.
I have to assume you are referring to the board level experimenter products that EML produced. I have a couple of the sample & Holds that I use in my SteamSynth, but beyond that, I don't know much.
I'll make a strong assumption however... You'll need to decide how you want to power your (rare) Envelope Follower board. I would NOT modify your EML synth just to bring out the required voltages.
I would strongly suggest a small external power supply, then simply connect the grounds of the two units.
