Excellent condition Acoustat 2+2 with Oak base and original black socks. No odd noises or quirks. Perfect working condition with no blemishes to base. Interfaces are MK-121A and are non Medallion. The bias circuit has been modified to 6kv from 5kv, which brings better high end and much easier load for amplifier. Can be removed if requested. Also installed a Neon Lamp "Charge Indicator" that lights up when a bias charge is sent to the diaphragm - this is identical circuit that is found on the Quad electrostatic speakers. It shows a slow blip every 20 seconds when playing music indicating no charge leaks.Only selling as I am making a custom 3 panel wide Acoustat speaker to replace these. Pick up in West Chicago suburb, or buyer pays for pickup and shipment. I can refer buyer to a trusted local company that will professionally crate and ship the speakers to you, at your cost.
