This is a DIY kit (or PCB only) for the popular Actidamp MkII phono preamplifier MM/MC. The circuit was published in Amaterske radio (CZ) 02/1990 and is often built by audio enthusiasts even today, thanks to its properties and parts used that are not made from unobtainium. PCB size is (180 x 77 mm) with black color. The circuit should be supplied from a 24-0-24 VAC transformer (not included). It has input from MC or MM phono (adjustable type and load capacity of cartridge by jumpers) and line-level output. Instructions how to complete it are on my web page.
