ARP Quadra Synthesizer For Sale or Trade - $9,999 (Valencia)

Vintage ARP Quadra analog synthesizer for sale or trade.
Cosmetic condition is excellent.
Powers on and produces sound, touch membrane works, but will need a recap and several sliders replaced.
I am open to reasonable cash offers as well as partial trades plus cash.
The only trade items of interest are a Prophet VS rack or keyboard, Voyetra 8, vintage outboard studio gear, high end effects devices, and vintage tube microphones.
Serious inquiries only.
