So some good researchers over at the Steve Hoffman Forum found this!!!
ROYAL DEVICE - BLUE EYES PHONO STAGE
COMPLETELY NO FEEDBACK even locally SINGLE ENDED CLASS A Junction FET PASSIVE RIAA PHONO STAGE.
The Blu Eyes RUBINA is derived from the professional RUBINA PHONO STAGE. It features a smaller cabinet in shining stainless steel BUT NO Step-up neither OUTPUT transformers. Suites to all MM and MC cartridges with an output level above 1 milliVolt, and it can drive even power amps with at least 0,5-0,6 volt input sensitivity. If connected to a preamp the possibility to drive also cartridges with output level of 0,5 millivolt is possible instead. The reason to use a JFET circuitry instead of tubes it is due to the high gain obtainable without the use of Feedback, still keeping a very low noise. Moreover, with discrete JFET circuitry we can afford valve sound without entering the microphonicity problems. Metalized polypropylene 2% capacitors used onto the PAssive RIAA circuit. Only discrete components. No ICs or SMD used at all. Please see schematics hereafter.
