I just made a phone call to my trusted old speaker tech/reconer  
John Harrison and was informed by his business partner  Thom  with shocking news that he had past away in his sleep earlier in the week.  I have done business with John for a few decades. This is truly SAD ______.  He was only 3 years older then me.

Sorry to hear of the loss of your friend.

Sad news.  I too knew John. The hemp cone Tone Tubby speakers he developed are fine speakers used by Santana, among many others.  John was a character and I enjoyed hanging with him when I found myself in his shop.
 
May the four winds blow you safely home.
 
Bill, tgo
