EAT E-Glo S Tube Phono Stage

E-glo S – is a hybrid phono preamplifier that utIlizes ECC83 tubes (twin triode) in the first and second gain stages In order to get higher gain and lower noise we use in the first stage a cascode connection of tube with with two paralelly connected low-noise J-FET transistors.

RIAA curve is equalised fully passive and splitted in two steps which allows to achieve perfect impedance matching between the gain stage and equalization block. Phono preamplifier doesn’t have any global feedback. It has a massive aluminium chassis, large possibility of adjusting the impedance, capacity and gain. It has subsonic filter with mild effect which doesn’t affect audible frequencies in unpleasant way.

A very important part is the advanced power supply that uses anode voltage regulation and a well filtrated voltage. Filtration is in three steps, this result is a perfect S/N ratio and undisturbed musical experience.
