ZEROZONE PA3 Stereo Single-ended Class A Power Amplifier Bare PCB Base On PASS A3 30W+30W

PA3 Reference the Famous PASS A3 circuit . All the FET are equipped same with the origianl machine, the input differential Transistors using the new U.S IRF9610, The power Transistors using the origianl N-channel IRFP250, FETs precision matching.

It has independent integrated power supply and SPK protection, and it does not need additional power supply board to supply power. Directly connect the transformer.

Sound style: Sweet and mellow, music taste very good, transparent.sound will be better than most of General amplifier.

Works voltage: AC 20V---0---20V (Each channel transformer power recommned above 200VA)

Output power: 30W+30W Pure Class A (8ohm)

PCB Size: 228mm*76mm

Warm reminder: The single-ended class A amp board heat Hugely. please don't connect power without out heatsink or with a smaller heatsink. or will burnt this board. It is recommended that the weight of the installed heat sink should not be less than 3KG per channel.

Note: This is a Bare PCB. All parts need to be matched by yourself.
