Stereo valve preamplifier.
Evolution Pre: the design
The Evolution Pre is the preamplifier made for the Triode integrated amplifiers that can run as power amps (Evolution, TRZ-300W), and it pairs with power amplifiers from other makers as well.
It follows the look of the Evolution series: central display, two knobs, black brushed-aluminium front. Supply, inputs, gain and outputs are separate sections; the volume control is electronic, the transformer is an R-core type and the valves are by JJ Electronic.
