if choose diy kit
DIY kit. all the parts will need yourself to solder and tested it.
if choose assembled board will receive tested headphone amp board
This is a very good small class A power amp kit, with Excellent Dynamic,Excellent low-frequency, and Flexible low-frequency.
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 capacitanceOutputcoupling capacitor straight Nichicon KG II file 3300UF, this capacitor can be a perfect match with the input capacitance
4Feedback 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.
6Power 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)
