A little on subject/off subject remark:
When I was 17, I blew a woofer in my brother's Sansui speakers playing The Big Sound of the Drags LP. I took them to the local audio saloon for repair and was told: "Sansui speakers aren'tt worth the postage to send them here from Japan!!" That was my first experience with an audio specialty store.
Then I opened one years later. Slow learner, I guess.
