Hi all,
Here is a Remote Control Copper Preamp.
I made this to go with my Brass El84 Mono-blocks but find I don't need it.
It uses the excellent PGA 2311 chip with micro processor control.
Three pairs of phono inputs and one pair of outputs.
Case made from 2mm Copper with Beech sides, Aluminium top holds the toroidal transformer.
Steam Punk style.:)
£90 inc p&p.
