Scheherazade MK2 line tube preamplifier

Scheherazade MK2 Tubes Line Preamplifier

Scheherazade MK2 is Audio Experience Level 4 line preamp.

The line stage use one NOS Siemens EC8010 gold pin tube with one Tango ISO line output transformer construct Low output impedance ,Class A and Not NFB for each channel.

The Scheherazade MK2 's application of a highly efficient solid-state voltage regulator with two EZ80 ( EZ40 ) Tube for current regulator in the HVB+ power supply . Also it use the external power supply get highest S/N.
