printed circuit board for the construction of a hybrid stereo audio amplifier with valve input and mosfet power output stage. the circuit requires a transformer with a secondary of 24vac 2Amper and a secondary of 9vac 1Amper.

the electrical circuit is visible in the photo, the components bom and the assembly plan will be provided.

dimension : 257x215mm .

power output : 10w/8ohm for channel , good also for headphone with low impedence

there is also an pre-out for other amplifier..
