Product features and technical parameters:
Circuit: Using the improved principle circuit of Hotan original version;excellent PCB circuit design, reasonable, regular, symmetrical device layout, strictly following the single-point grounding routing.
Chassis: A dedicated chassis specially designed for the Hotan pre-stage, with a fully aluminum solid core knob.The entire box is made of aluminum,
Transformer: A horizontal transformer with a power of 120W (EI8642/H50 chip) with a side cover is used. The primary and secondary windings are strictly shielded, and advanced vacuum varnishing methods are used at home and abroad to achieve a transparent and tight varnish.
The power filament/left/right channel filaments are separately powered by independent windings to prevent mutual crosstalk
Potentiometer: Original 16-type potentiometer from Japan ALPS
