20W Audio Power Amplifier Board MJ5024 MJ5025 DC Class A Radiator Aluminum Plate for DIY 2Pcs
Specifications:
- Original MJ5024, MJ5025
- The main circuit of electrolytic capacitor is famous brand.
- Capacitance 2x470UF/100V
- Five ring metal resistance, main circuit accuracy is -+1%
- PCB thickness is 1.6mm, copper thicknes is 2.0Oz
- UPC1237 peaker protecting circuit
Parameters:
- Power coltage: DC-+25V to -+35V
- Output power: 20W@8Ohm, 4Ohm@40W, 2Ohm@80W
- peaker impedance: 2-8Ohm
- PCB: 181*65mm
NOTICE:
- The plate is aluminum radiator, CNC processing. But also need radiator when in parallerl.
- There is test points TEST on amplifier board, white power resistance is 0.22 ohm, if TEST is 22MV, then static is 100MAX2 = 200MA, because X2 tubes in parallel. Clockwise reduces quiescent current, counter-clockwise to increase the static current.
Package list:
- 2 x Amplifier Board
