Design of materials:
- 1mm thickness steel plate using black spray process box .
- Using 8mm thick aluminum wire drawing process panel.
- The metal knob cap.
- The blue power indicator tube .
- power supply with low magnetic leakage toroidal transformer power supply.
- The volume is controlled by Taiwan WL or wizard potentiometer.
- Signal input shielded signal lines.
- The red Weimar, Germany WIMA MKP polypropylene capacitors coupled to do before and after class .
- pre-amp use 6J1 tube , which is an indirectly heated high gain beams shoot pentode , transparent sound bright , airy grainy good, then a transistor form , lower distortion , better sense of hearing .
- Power amp section selected U.S. National's reputation tube flavor amplifier chip LM1876T, NS company has patented SPIKE sudden loss of instantaneous temperature protection circuit , overvoltage , undervoltage , overload protection, and monitoring transistor safe operating area protection, fade in, fade out squelch mode
- tube pre- regulator power supply uses high pressure to make noise to a minimum level .
- AC-powered filament and balanced ground , while maintaining the advantages of AC-powered warm timbre , and overcome the shortcomings of the DC power supply lead voice hardening and aging fast filament end .
- use of mature experience designing large power amplifier , so that the machine layout is very reasonable , although our whole range of products in the low-cost mini- amplifier , but in tone , SNR , frequency response , power and so it is not distorted admiration.
- The machine has increased the latest improved amp output function , the driving force is good, can be connected to 32-600Ω impedance range headphones.
