Update via the comments: "Electrically they're fine. Mechanically, they could use some help. Boards held in place with hot glue (and the wrong type that doesn't stick well to smooth surfaces), various pot shaft types, poor strain relieving, thin metal, etc. Wonderful in the design, poor in the construction. Fwiw, I've serviced at least 5 of them. Anyone that buys one should open it up after shipping and before powering up. The boards inside can flop over onto each other and short out."
Update: Be sure to check out the comments. Supposedly, this is
Thighpaulsandra's Fenix. Link to studio shots

No title link. Two shots and details pulled via
this auction. Sent my way via Vincent.

"Very rare semi modular synthesizer, one of only 75 designed and built by the original Synton team. A direct descendant of the Synton 3000 modular synthesizer and the Syrinx lead synth. Almost every module is unique: this means that every LFO and Envelope Generator (and most mixers, VCO's, VCF's) have different controls and ins/outs. The Fenix uses industry-standard 1 V/octave for pitch control, and positive gate signals. Internal audio levels are 4 VPP, control voltages are -4/+4 or 0-8 Volts. Uses sturdy banana jacks for patching.
