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.
