Introduction:

Pass aleph-M amp board is a Pure class A power amplifier board, The finished product output power 16W 8R suitable for pushing all kinds of bookshelf boxes and antique boxes. The sound is sweet and close to the Tube amp machine. This circuit has few components. It can turn on the sound without debugging as long as it is installed as required.

 

This circuit is a reduced version of Pass 5 and A2. It use pair of power tub transistor,wtithout A2's Big chassis and the matching problem of output transistors. The voltage is also reduced to +/-18V and the power supply output is 16W.


All adopt the original model MOSFET tube, the input differential tube adopts U.S new IRF9610, the power tube adopts U.S new N-channel IRFP250, and the input and output MOSFET tubes undergo Precision pairing (1% precision).

Focus on the feedback capacitor, use the new ELNA + Nichicon, dynamic and strong guarantee.

Sound style: sweet and rich, music is very good, transparent, sound can exceed many power amplifiers.

 


 

Works Voltage: +/-18VDC

Input: Support Unbalanced and balanced input.

Output Power: 16W each board at 8ohm load.

PCB size: 117mm*60mm
