HiFi 200W Class AB /A Stereo Amplifier DIY Accuphase P-1000 ON MJ15024 15025

Description: HiFi 200W Class AB /A Stereo Amplifier DIY Accuphase P-1000 ON MJ15024 15025 Fully assembled, Delivery 200W Class AB power output,Can work at Class A Up for presenting is an assembled power amplifier board,The circuit is refer to Accuphase P1000 Hi-End amplifier, Accuphase A100 and P-7100 is the successor with almost same circuit. The amplifier featured with current negative feedback and DC servo, It has great dynamic and thunder alike speed, Also refined and rich details. The output stage using MJ15024/25 high performance transistor with metal package(250W Pd), It is more better than original design of 2SC5242/2SA1962 with 130W Pd. Reminder: 10000UF/63V filterring capacitor is optional, Please choose in as your needs. It can be NICHICON KG or ELNA for audio, Please contact us if you want to upgrade,Thanks. Adjustment Measure the quiescent voltage on the white resistor close to MJ15024/15025, Devide the voltage drop on 0.25 Ohm resistor to get current value, For example, If the voltage on 'Test' point is 25mv,The quiescent current is 25mv/0.25 =100ma.Set the voltage drop between 20mv to 200mv, Bigger heatsink is required for bigger quiescent current. Features Hi-End grade MJ15024/25 output power transistor from ON semicondutor Driving stage is MJ15032/33 transistor from ON semicondutor Volate amplifing stage use TOSHIBA 2SC1815/2SA1015 and HITACHI D669 B647 Most resistor is in military grade from national owned BEIJING 718 factory, Copper leads. Some are PANASONIC. OMRON relay for speaker protection Capacitors are from WIMI / NCC / NOVER / RIFA / NICHICON SANKEN 50A recitfier bridge NOVER 10000UF 63V filterring capacitor in audio grade Specifications Power supply: AC (24V to 38V)-0-(24V to 38V) Working type: Class AB, Can be class A by adjusting the varible resistor. Power output: Class AB 200W at 4 Ohms, 130W at 8 Ohms Frequency response 5hz - 100Khz (+-3Db) Input sensitivity: 2V Input impedance: 20K ohms S/N ratio: >100Db PCB size: 188mm * 145mm, The overall size is 188mm*160mm with metal L angle Packing List One assembled amplifier board About Chinaaudiostore We are a team of audio enthusiasts, We are proferssional in analog and digital electric, More than just reseller.
