High-fidelity home fever professional stage
11 pair C5200 A1943
large watt 1200W amplifier tube amplifier board
Technical parameters:
To achieve the highest resolution, the board uses a mono amplifier structure. Each has a separate protection circuit
So the board supply voltage range is extremely wide, can work reliably between the DC dual 28V-110V (bare board recommended operating voltage intermediate
value dual 55-volt DC, as power transformers, of course, the bigger the better).
Voltage:
28-110V
900W or more
Size:
305mmX78mm
Output power:
8Ω 1200W, 4Ω 2400W
Frequency Response:
Total Harmonic Distortion:
SNR:

Introduction:
The board for the pursuit of clear, pure sound, input using IC processing , specifically the use of high-frequency transistor circuit design, the transistors that consistently crisp and clear sound in the end , to promote the level uses audio-specific tube C5200, A1943 to serve,Power output stage 10 pairs of audio-specific tube
C5200, A1943 parallel output
this board is truly original pairing tube , or to ensure the effectiveness of the high pressure and impatience,
Preclude the use of thick board 2.0mmFR-4 high-grade circuit boards, resistors with precision error of 1% metal film resistors imported from Taiwan , a small capacitance capacitors used in all original , coupled with advanced capacitor. The plate material stress, rational circuit design , very high -noise ratio, sound pure and sweet , detail outstanding. I would urge Taobao Shaoyou assured purchase this : a small volume will be able to push hard Swans pair of friends dripping try to push
the bass with low distortion , low noise, high pressure and mute switch
, with a perfect chip over voltage protection , overload protection, output short circuit protection. sounds pure and bright , without the use of materials and components on the ratio. Circuit design further perfection. High -noise ratio, it is difficult to hear noise closer to the speakers .
Note : If you choose C type, Because the weight exceeds 2kg, Cannot be sent through China Post packet,The seller chooses the right shipping method.
