Gramophone / pick up preamplifier. The '33.3', this phono stage has been designed for the absolute best sound quality per £.  It is designed and hand built in Lancashire, and boasts some sound enhancing features. Obviously all valve (2x ECC83 double triode Class A operation). Each channel is assembled on it's own, mono construction if you like. The shortest signal path possible, with no need for internal wire or connections, maximising low level detail and lowering distortion.  All components are very high tolerance and very carefully selected. All are hand made, and all are subject to 100 hour burn in and test. The design was to make longevity and low noise a priority over absolute gain. Unlike some of our competitors, the sound quality of the '33.3' will not deteriorate with age. The circuit uses active RIAA equalization, again using the highest tolerance matched components throughout. Specially selected valves have been fitted. For more technical stuff, please scroll below pictures. Power mains inlet fitted as an IEC inline socket.
