Steve Gifford Posted September 24, 2018 Report Share Posted September 24, 2018 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 had never restored a set of speakers before but thanks to the encouragement of Roy, Glenn, Kent and others on this site, 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 from captainfantastic07 on eBay. - Cabinets sanded and hand-rubbed with Watco Danish Oil (Dark Walnut) and finished with four coats of Minwax satin polyurethane. - Woofer perimeter and bolt holes resealed with speaker sealing caulk from Parts Express - Original plastic speaker grill frames replaced with more durable 1/4" Masonite for easier installation and removal. - Masonite speaker grille frames spray painted flat black before wrapping with fabric to prevent frame being seen through fabric. - Reproduction speaker grille saran material from Q-Components in Canada. - 3M automotive trim adhesive tape followed by ¼” heavy duty staples to prevent slipping of material or fraying of fabric edges - Reproduction “AR Inc” and "3" pin from jKent Attached are a few pictures so you can see before and after and some of the steps along the way. I plan on enjoying them for a while and then will probably try selling them locally before putting on eBay to avoid the hassle and potential damage associated with shipping. Thank you to Roy, Glenn and Kent for all of your input and for the wealth of information everyone else has contributed to this site! If you have any questions or comments, please let me know!
