They have been used lightly in my home since then. The serial numbers are 99261 & 99262. Twelve years ago the woofer cone surrounds were both renewed. The mid-range and tweeter potentiometers have always been a little noisy and would be candidates for a service, but otherwise all six speakers are functional. The cabinets are in good condition for their age. The walnut veneer has fading on some sides and a small amount of termite damage in one spot (see pictures). They would be good candidates for refinishing. When my daughter was an infant, she was fascinated by the “AR-3a” badges and I removed them for her safety. I never replaced them and now (living with my daughter) I can only find one of them, which will be included. They are in their original boxes with original packing.
