Product Details:
The 2A3 vacuum tube was developed by RCA in the 1930s. It is a typical direct heating triode power transistor with low internal resistance, good linearity, and wide frequency response, making it a very good vacuum tube..
1:) All adopt AC filament lighting, producing a lively and vivid sound. The AC noise is extremely low
2:) 6N8P drives 2A3 (45), with an output power of up to 5W×2 or more. It is suitable for driving loudspeakers with an impedance of (4-8) ohms and a sensitivity of 90db or higher..
3:) The electronic tubes all operate in Class A amplification state, resulting in minimal distortion, sweet and mellow sound, and extremely high audibility.
4:) Using 1% high-precision metal film resistors and imported electrolytic capacitors.
5:) CLRC multi-level filtering, high signal-to-noise ratio.
6:) TE MKP thin-film copper-pin capacitor boasts a rich and mellow tone, with a delicate and transparent high frequency!.
7:) The layout is reasonable and neat, stable and reliable.
