[BC] Re: Early Multiband

[DHultsman5@aol.com]

Barney Grant in SW Alabama built a two band compressor using three Collins  
plug-in AGC units in the early '70's.
 
My first experience with the Dorrough multiband was at KRLD in Dallas it  was 
one of Mike's early prototypes and used the OpAmp Labs  modified  Limiter 
modules with his active filters.  We used it as a multiband  compressor prior to 
our Gates Solid Statesman on our GE 50 kW.
 
Later on we bought two of his first silver panel models.  Early '70's  sticks 
in my mind.

Altec!  That was what I was trying to remember.  Mike's  experiments 
at KGFJ were also in the late 60s, but we didn't build  anything you 
could call "production" until 1970/71.
