Alpha Juno 2 mods?

[CHoaglin at aol.com]

I recently picked up a Juno 2 and have been fixing it up (cleaned out the 
ashes, changed the power jack to a standard 3 prong etc..)

>From what I read and looking inside, I gather that it's an hybrid synth with 
DCO's. I remember seeing a 5517 inside (that's the filter, right?). It's not 
a great synth, as least not as good as my JP-8000, but, as much fun as the 
alpha dial is to spin, I'd like to add some real knobs to it for controlling 
the frequency and resonance, among other things. Preferably, I'd like to 
retrofit it with as many realtime controls as possible as opposed to menu 
driven. If anybody's got schematics for it, or knows of any modifications, 
I'd love to know about them. (I could reverse engineer it and draw my own, 
but that would take time I don't really have right now with my academics)
