The Real phono MK3

The Real Phono MK3 Phono Amplifier.

Flagship grade phono amplifier.

The main stage with external power supply , two unit design.

THE REAL Phono MK3 use T-LCR type RIAA EQ design, the T-LCR Type is best method for revive RIAA EQ, also is highest cost design.

The new design input stage is 6DJ8 tube direct coupling to NOS Siemens EC8010 tube driver Hasimoto line output transformer , special made T-LCR type RIAA EQ , 5687WB tube driver Hasimoto line output transformer for output stage( with XLR and RCA output).

THE REAL Phono MK3 's application of a highly efficient solid-state voltage regulator with EZ80 Tube for current regulator and Hasimoto choke in each HVB+ power supply . Also it use the external power supply get highest S/N. The power supply is dual mono design, each channel with two separately HVB+ power supply for input stage and output stage, so the power with total four separately HVB+ power supply

It has two pair MC-step up transformer , They are Hasimoto HM-7 ( made in Japan ) and Jensen JT-347-AXT(made in USA) top model MC step-up transformer .
