PWK MAIN AMPLIFIER - Klipsch Museum Of Audio History
Here is a recent find from the Klipsch Museum Of Audio History. I eroniously posted this as a PWK Brook mod but upon further inspection this is a different amplifier. It is not odd that PWK designed and built an amplifer as he was building everything he used including turntable, cartridge, and tonearm. The early days of Klipsch were very lean financially so this makes sense. This could have been 1940's or 1950's
Here is a drawing with a few extra notations.
Jim Hunter and Kerry Geist recently desicovered an example of the amplifier burried in the Klipsch Museum Of Audio History basement. Since there is one perhaps it is from the days of mono.
