Hi all! Just joined the forum! I had a Aiwa CA-70 back in the early to mid 80's. Bought it with my hard earned cash(mowing grass probably). My Grandfather liked mine so much he bought one too! Mine is long gone, used the heck out of it! But my grandfather(now 92 years old) still has his. It quit working 10+ years ago. Been sitting on a shelf in his basement since. I am guessing all it ever needed was belts, but I noticed over the holidays the left woofer surround was gone. Right one still looks good. Didn't get to check out the passive radiator. I am hoping to gather some info and gain some connections to get it up and working again. It is in near mint condition physically. He takes extremely good care of hes stuff!
