I thank my Dad, as well, but at least one generation removed from your experience.
I "inherited" my Dad's mono JBL 030 system when he left it at the curb for Goodwill and I schlepped it into my closet for safe-keeping! Over 60-years later, I still have his mono JBL box and the used C37 mis-matched-cabinet audio-twin to it I purchased back in the '60s. But, I also have a pair of empty C35 cabinets I had shipped in from the west coast over 20-years ago for the sole purpose of building my Dad's originals into a matched pair of vintage JBL stereo speakers. That's a project for this year. The cabinets have never been in my house since picking them up from a freight depot about 20-miles away and stashing them in a friend's nearby basement for safe-keeping. Time for them to come "home".
It's a few months early, but Happy Father's Day!
