Acoustic Research AR-3 Demo

These speakers were given to me by a friend of mine at church who had them in the back of his truck destined for Goodwill. The cabinets were fairly rough and the grille fabric had been replaced but everything else was original. I have spent the last 6 weeks restoring them and am very happy with how they turned out. Here are a few of the details:
Year: 1963-4
Make: Acoustic Research
Model: AR-3
Serial #s: C21604 & C21611
Restoration summary:
- Original dual 24uF and 6uF paper capacitor replaced with new Solen 24uF 400V and Dayton Audio 6.2uF 250V Precision Audio capacitors from Parts Express
- Original 16 Ohm / 25 Watt wire-wound potentiometers were corroded beyond repair and were replaced with modern reproduction wire-wound potentiometers of the same size and specifications
- Cabinets sanded and hand-rubbed with Watco Danish Oil (Dark Walnut) and finished with four coats of Minwax satin polyurethane.
- Cabinets resealed with Parts Express speaker sealing caulk and meet original specs for air-tightness.
- Original plastic speaker grill frames replaced with more durable 1/4" Masonite for easier installation and removal.
- Reproduction speaker grille saran material from Q-Components in Canada.
- Reproduction speaker grill logo screen-printed on brass as original
- Reproduction "3" pin CNC cut from brass alloy in same font and size as original
