Pre -AMP with amplimo modules..

 

This is a pre-amp I once build, the electronics are almost completely in te black Amplimo modules you see on the big picture. All the other electronics are either supply or potmeters. The wiring is mainly done with threads from a IBM CAT-5 network cable. It's a very flexible pre-amp with both bass and treble control (+ or - 20 db). I don't use this pre-amp anymore though, nowadays I prefer to connect the cd player via only a potmeter to the end amplifier.
