Paia Custom Analog Synthesizer 1972

via this auction

"Here we have a one of a kind custom PAiA built into an old suitcase built By Steve Alcorn the vice president of engineering at Linn, the synth is an expanded 2700. It inludes original 1/4" patch cables, suitcase has a key and there is another key to power the synth on. Comes with every pamphlet for each module used. Steve also signed the outside of the suitcase.

Steve pre-wired it up like an Arp Odyssey It is still completely custom-patchable as well. Modules include:

Voltage-Controlled Oscillator (3)

Voltage-Controlled Amplifier (2)

Voltage-Controlled Bandpass Filter

Voltage Controlled Low Pass Filter

Envelope Generator

Control Oscillator / Noise Choice

Power Supply

Glide Retro Fit

Envelope Follower / Trigger

Sine Converter / Pulse Width Modulator

Balanced Modulator

Envelope Generator

In addition, all the original manuals are included for the above modules, plus a few other of PAIA's products.

The unit is designed to be easily ported to gigs, where in a few seconds the keyboard can be lifted out of the case cover and the case cover detached, giving you a Moog-like setup. It was a fun performance instrument. I remember generating the crashing waves for Riders on the Storm during a gig in 1973!

This unit has not been powered since the late 70s. Prudence would suggest a thorough inspection of all the electrolytic capacitors, for starters. But this would be a dream project for an electronics tinkerer, and gives you a very large collection of very rare PAIA circuits as your starting place."
