2SA1943 2SC5200 Mono 400watt Audio Power Amplifier with Thermal Protection & Speaker Protection Full Ready Board

2SA1943 2SC5200 Mono 400watt Audio Power Amplifier with Thermal Protection & Speaker Protection Full Ready Board. PRODUCT DETAILS OF MONO AMPLIFIER READY BOARD 1943 5200 HIGH 400W AMPLIFIER 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-90V 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 20-90V (the upgraded version has optimized the circuit and parts, but To directly apply high voltage, it is recommended to use below 90V, do not challenge the voltage limit. ) Without 1943 & 5200 Transistor(Eight Transistor Board) & Heatsink. Maximum Input Voltage: DC 48v-0-48v, 6 to 10Amp. Including Thermal & Heat protection & Cooling Fan connection. Same as picture. No change & return will be acceptable after unpack the products. We checked the products before packaging. PCB Size: 195mm X 60mm Duel Layer PCB China & Assembly in BD.
