Description

No.8.0b is an Update of No. 8.0 whose external appearance is same.

The improved items include circuit structure, parameter, chosen components, arrangement for circuit board, inside construction and electromagnetic radiation, etc. All of these make it more rationalized and reach an anticipative design purpose.

No. 8.0b uses the PCB with copper foil of 2ounce. It adopts large-area ground screen and widens fused stannum at the place where large current goes through. It employs Japanese Toshiba high power transistors, RUBCON MUSE electrolytic capacitors, German WIMA MKS capacitors and customized polystyrene capacitors and metal film resistors from appointed factory. The resistors that are relevant to closed loop use metal resistors with error amount of 1%. High power resistors are Japanese KOA foil non-inductive ones. R-shaped 260W transformer is specially designed. There are double power supply system, electronic filtering in voltage amplifier and full-function IC protection circuit. Its front panel made of sheet aluminum is 10mm in thickness. The chosen transistors brand names and models were compared over and over again before they ware adopted.

No. 8.0b’s sound representation is: Full and mellow at low frequency, rich timbre texture at mid -frequency and high frequency with charming musical richness. So it can match well various kinds of loudspeakers.
