2SA1943/2SC5200 200W+200W Eight-tube High Power Poard without Heat Sink

Description:
All parts and components of this product are original products, unpretentious and pure in quality; the use of high-quality original parts not only guarantees safety and quality, but also has a long service life, and more importantly, it is a strong guarantee that the actual performance can reach the design goals.
Features:
1. This power amplifier board is composed of four original 2SC5200 and four original 2SA1943 high-power power amplifier tubes. Stable performance, strong power, very low noise.
2. The rectifier filter circuit is 4 pieces of 50V4700UF filter capacitor and high-speed rectifier bridge silicon 25A. 3. Use high-precision metal film resistors and high-quality capacitors. This price does not have a heat sink. 4. Full-function protection circuit 5. Because this board uses direct-coupled test amplification, the entire circuit has no coupling capacitors, which reduces the distortion to 1%. The overall sound test feel is (the low frequency is heavy and powerful, the midrange is full, the high pitch is sharp but not prickly, the electric current is very small, and the ears stick to the horn to hear) feel the fun of audio fever.
