Product Description :

Note: DIY Kits need to be soldered by yourshelf. The finished board of working voltage is  DC 24V and the quiescent current is 30-50MA.

 
1969M FET tube power amplifier board uses a dedicated field effect power amplifier tube, the power amplifier tube is the original dismantling tube to better ensure the sound quality, the vocals are sweet and delicate, the bass is strong and flexible, and it is not tired for a long time.
 
Electrolytic capacitors use a brand new original Japanese (Yina, Chemical, Panasonic, Nikon) audio electrolytic capacitors, pure sound, original flavor.
 
The IRF630 and IRFP448 field effect dedicated power amplifier tubes are used, which are more professional, stable in operation and sound better.
 
The position of the midpoint voltage and the quiescent current is adjusted, and the vertical or horizontal output capacitor can be replaced at will, and the circuit board can be installed at will, which greatly improves the playability, convenience and randomness of the hobbyist.
 
 
Adjust the midpoint voltage and quiescent current usage:
 
1.TZ1 adjusts the quiescent current corresponding to T1. T1 is connected to the ammeter at two points. Adjusting TZ1 makes the current 30-50ma (the sound quality is very good). If you need to adjust the quiescent current, the radiator will increase accordingly. After adjusting, you can short the position of T1.
 
2.TZ2 adjusts the midpoint voltage corresponding to T2, T2 is the adjustment point, and adjusts TZ2 so that the voltage of T2 point to ground is half of the power supply voltage.
