Is anyone aware of the custom system built 1975 in Palo Alto for Barney Oliver, the Hewlett-Packard Research Director?
The speaker system used JBL's in a concrete horn permancnetly poured in his basement included D-130's. I heard this was a birthday surprise by the engineers who worked for him but don't know how they could accomplish the surprise part.
The amplifier, later made available only to hp employees for $400 parts cost, was assembled after hours in a labor of love in the research lab. It still has the best overall specs for a SS amp especially distortion. It was designed for the Shure V15 type 3 phono cart but had other inputs. Hi and lo cuts but no operator tone-type controls. Only 200 were made available. At full volume there are NO noise clicks when changing any switches. Normal listening done at 2-3 (10).
Anyone ever seen pictures of know of this system?
I have one of the amplifiers, known simply as a Barney Oliver Amplifier.
