PRODUCT DETAILS OF MONO AMPLIFIER READY BOARD 1943 5200 HIGH 200W AFTER THE TUBE AMP BOARD – UPGRADE AUDIO SYSTEM HIGH-PERFORMANCE MONO AMPLIFIER READY BOARD Product details of Mono Amplifier Board 1943 5200 High 200W After Tube Amp Board1. The board is a single-channel amplifier board, which requires dual-channel2. The circuit design uses A970/C2240 high-voltage audio pair tube dual differential circuit and A1145/C2705 for voltage amplification to promote the use of mid- pair tube A1837/C4793, and the output stage uses A1943/C5200 high- Toshiba pair tube.3.Wide supply range, DC plus or minus 20V-35V can be, as long as enough is supplied to easily reach 200, the sound quality is good, the driving force is strong, and the 15-inch speaker is pushed without pressure!4. supply: dual voltage, DC plus or minus 20-35V. With 1943 & 5200 Transistor. Same as picture. No change & return will be acceptable after any soldering on PCB. For any query chat us before order. Dual Layer PCB China & Assembly in BD.
