HIFI A6 HD1969 Pure Class A Stereo 25W+25W power amplifier board

Product details:
 

The sound quality of Class A HD1969 is recognized by everyone. This version using ON MJE15024 25 gold seal transistor driver, the circuit is optimized, the output power and current are greatly improved, and the maximum output power can reach 25W.

Each channel uses a three-tube solution, two of which are electronic buffering filters, which can avoid the impact of the loud speaker when the machine is turned on and off, which is a good protection for the speaker.

◆ Input voltage: AC 15V --- 28V (Recommended input voltage: AC 0--25V, 0--25V)

◆ Speaker: 4 --- 8Ω

◆ Main filter capacitor: NOVER 10000uF/50V *4 PCS

◆ The quiescent current is set to 1.2A by default. 

NOTE: 6 PCS gold-seal tube is a second-hand disassembled old tube, and 100% original test is OK.
