Hi Steve Eddy,
I like the buffer circuit. I wonder why it needs +/-10 and +/-20 volts. Could it be converted to only higher voltage supply with just two more resistors? I am no expert, but some here could have a look at it and tell me.

sadly the original wood sides and top are missing but the screws for the wood sides were located...the wood sides are probably tucked away somewhere in our massive warehouse.

I can not even begin to believe something like this could be accomplished in today's corporate environment. I feel good that the generation I am from was the same as this group. We need more ideas like this. People actually gave of themselves to make this happen. Not just a bunch of emails and promises.
I wonder how many of the original units are still usable today?
Thanks for digging this article up and sharing.

I worked at the plant where the Barney Oliver amplifiers were built in the 70's, and have one in perfect condition. DOes anyone want to buy it?

Make a bid. I don't know what shipping will cost, but I can find out. It is heavy.
