Product Q & A
Review


This is a very good small class A power amp board, with Excellent Dynamic,Excellent low-frequency, and Flexible low-frequency.

(the price is for 2 channle board)


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 not superfluous to increase electronic filtering, can enhance the dynamic

3:
Input coupling capacitor Nichicon MUSE BP 47UF large coupling capacitance,Output coupling 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 dynamic and 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 include:  Assembeld PNP sanken A1216 JLH1969 single-ended class A power amp board   X 2 channel
 

Note: this is a assembled and tested board.
