As of today (4 October 2020), this Audiophonics web item (Ref 11645) is described incorrectly. Of the two linear power supply modules I received in September, neither had an LT1083 regulator installed. They both came with an LT1084 small plastic format. Furthermore one of the regulators was not bolted flush with its heatsink, standing in free space 1.5mm away. Easily fixed, sure. But very poor quality control. As we are dealing with voltage and current (and sensitive, costly connected devices), please check your item carefully once it arrives. Enjoy!
