Description
2SA1943 2SC5200 8 Tube High-Power Board AC28-32V Input AC Power Amplifier Audio Tube Amplifier
Product Description
This power amplifier board consists of 4 pairs of original 2SC5200 and 2SA1943 high-power Japanese Toshiba power amplifier tubes. Stable performance, strong power, very low noise, hard to hear! The rectifier filter circuit is four 50V10000UF filter capacitors and a high-speed rectifier bridge of 25A. High-precision metal film resistors and high-quality capacitors are used. The price does not include the heat sink. Full-featured advanced speaker protection circuit Because the board adopts direct-coupled test amplification, the whole circuit has no coupling capacitor, which reduces the distortion to 1%. The overall audition feeling is (the low frequency is heavy and powerful, the midrange is full, the treble is sharp but not harsh, the current sound is very small, and the ear can only be heard when the ear is attached to the speaker) to experience the fun of audio fever.
