V18 PNP Sanken 2SA1216 JLH1969 class A power amp kit 10W+10W amplifier DIY
Note: this is a DIY kit, include 2 channle board. all the components need yourself to solder and adjust.
This is a very good small class A power amp kit, with Excellent Dynamic,Excellent low-frequency, and Flexible low-frequency.the V18 version has integrated with Rectifier power circuit. the main Filter capacitor are using 10pcs Japanese chemical 6800pf/25V.
PCB Size: PCB Size:76.5*119mm (W*L)
recommned input voltage: Single AC15-18V
recommend transformer power above 100VA.
output power 10W+10W (at 4ohm load)
Highlights：
1:Mono structure, easy to use the chassis two side heatsink to obtain a better cooling effect,
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 Panasonic 3300UF/25V.
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.
Debugging：
step1: first not connect the "TEXT" Jumper, and Series connect a Ammeter between this two point, adjust the "102" to make the Ammeter value about 1A.
step2: shorted the "TEXT" Jumper. test the "TEXT" jumper point to "GND" voltage as "V". then adjust the "104" to make the "TP" two point voltage
about 1/2 "V".
