This pre-amplifer is one of the most advanced pre-amp we have builded.

It has very precise power regulation and that will be the prerequisite for high quality sounds in your house.

Two US army signal transmission-line transformers 661712 can provide balance or unbalanced output. Pic1 Pic2 Pic3

Two pairs RCA Inputs.

High quality blue shell ALPS dual gang potentiometer volume controller.

High quality American made oil-filled capacitors coupling.

Based on the oil-filled capacitors as power filter, the quality of sound has reached another new level when compare those amps use electrolytic capacitors. 30μ450V AC(900V DC)
