PNP Sanken W0302 JLH1969 Single-ended Class A Power Amplifier Kit 10W+10W
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)
This is a DIY kit, all the components need yourself to solder and adjust, we can provide adjust Instructions via email.
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 capacitanceOutput 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 ON NJW0302.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)
