1pc Dynalo MOD Balanced Headphone-Amplifie Kit DIY
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .
To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required.
Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve problems by yourself.
Tech highlights：
True balance, cross negative feedback, withfour channel amplifier.
All-discrete fully-complementary topology.
No integrated circuits used except for the DC servo opamp and voltage regulators.
Complementary push-pull output stage.
DC servo.
PCB SIZE:125X150mm
Power requirements: Best:AC 15-0-15; 30VA

Based on the well-tested board on the standard version kit, we verified all key points' voltage, and used the signal generator and oscilloscope for analog waveform double verification. We will not use this board for listening test.
Schematic & key point of debugging
PCB comes with component parameters for easy installation.
We only refer the schematic of the amplification part of the circuit. If you need full circuit parameter, please read the component value with the PCB by yourself; we do not provide additionally.
please keep test point voltage close enough to it, +-20% is also permitted
