350C

Sound quality: delicate and smooth, with high resolution; the sound is clear and transparent, featuring a gentle, linear texture typical of Western electronics.
? Its efficiency is slightly higher than that of 6P3P; it has the sound characteristics of the FU-7 (807)
? The glass envelope of the 350C is larger than that of 6P3P/5881A, which improves heat dissipation and leads to more stable operation.
? It is suitable for use in push-pull configurations for high-power systems ?C the Newdek V10 uses two 350C components per channel in push-pull configuration, delivering 2??30W of power with a frequency response ranging from 10Hz to 70kHz.
