JCA Circuits Since 2006. Jason Arthur, Pottstown, Pennsylvania.

The JCA Circuits GR 1.6 “Golden Ratio” Amplifier is the first amplifier offered. I have plans and am presently working on another amp design TBA. The GR was introduced in January 2006.
I hand build each GR here in my shop in Pottstown, PA, USA–they are designed, built, and sold by one guy–me. There are no compromises in myshop. I sign and date the interior chassis of each amplifier I create.”
