Amare Musica Entropy amplifier

Amare Musica Entropy is a one of very few in the world all DHT amplifier (directly heated triode). Amplifier is build in dual mono power supply topology and each tube to prevent longlife and low hum have stabilized heating voltage by specialized current source module designed by Amare Musica…
In cathode circuit we uses CCS (http://en.wikipedia.org/wiki/Current_source) Each components are carefully selected like Jensen coupling capacitors in signal path. For volume control we uses Dact stepped attenuator which is driven by stepping motor, which can be controlled by remote control (volume control is designed exclusively by Amare Musica). For all logic i.e. selected input, earlier mentioned volume, delayed start anode voltage, etc is responsible IC specially designed for this purpose, all informations are displayed on DotMatrix. Exclusive remote controller is fully designed and build by Amare Musica (pcb’s, chassis, code etc). Output transformers are hand wound, with secondary winding are made with pure solid silver wire from United Kingdom.
