his is a DIY kit, all the components need yourself to solder and adjust. 

PCB Size: 75X50X1.6MM     1OZ copper

recommned input voltage: Single DC25V  

transformer power above 80VA,

output power 10W+10W (4ohm)

 Highlights：

1:Mono structure, easy to use the chassis two side heatsink to obtain a better cooling effect, if the use with ZERO-ZONE specially made HPOO power supply board,easily get completely independent dual mono channel, the rationale thereof 100%separation.

2:Taking into account only to do pure amplification stage, this version is notsuperfluous to increase electronic filtering, can enhance the dynamic

3:Input coupling capacitor Nichicon MUSE BP 47UF large coupling capacitance，Outputcoupling capacitor straight Nichicon KG II file 3300UF, this capacitor can be a perfect match with the input capacitance

4：Feedback and bootstrap capacitor using ELNA CERAFINE, in order to have a dynamicand intensity, the two capacitors must be on ELNA CERAFINE.

5: The input stage transistor is very important, we prefer Toshiba C2240BL.

6：Power transistor using original Sanken 2SA1216.The sound is very good.

Note: the class A amp heat will be high. please must install a big heatsink before power on.

(the heatsink recommned size:246X30X90mm)

Package Included:
