The TUBE 53 is the CEC’s first vacuum tube amplifier which achieves a 20W + 20W (8Ω) output. It offers high-power, high response and the ability to drive analogue signals with ease, even from digital media players.
The TUBE 53 uses the 6L6GC vacuum tubes for the output. The 6L6GC is known as a compact, high-power and high-speed tube based on the 6L6, designed in the 1930’s by the RCA Company in the USA. Several modifications enabled spectacular improvement in the stability and reliability of the tube, giving the 6L6GC the ability to satisfy modern musical demands such as high-power, high-speed etc. The 6L6GC is also well-known as a guitar amplifier tube, helping create countless legendary moments with big brands thanks to its remarkable musical characteristics.
The TUBE 53 uses two 6L6GC tubes per channel in a push-pull configuration, and the power amplifier circuitry is designed in the Mullard type with low-distortion for the phase inverting. The auto-bias setting results in a long service life for the tubes. The TUBE 53’s minimum reliance on negative feedback circuitry enables hifidelity music reproduction.
The TUBE 53’s output transformer, made from orient core materials, enables a straight sound quality with minimum phase misalignment. The use of an additional troidal transformer for the power supply offers superior rise characteristics. Noise is thoroughly eliminated by solidi- fying the transformer with resin and covering it with a steel casing.
The TUBE53 uses selected high-quality components to draw out the circuitry’s full potential, such as low-distortion volume control, electrolytic capacitors and resistors with high information processing ability and low noise.
The design concept for TUBE 53 aims for a unique combination of the latest technology and traditional analogue technique. Ample use of pure aluminum for the chassis contributes greatly to both its sophisticated appearance and musical performance. The slim and modern appearance fits right in with CEC’s existing 53 se- ries. The soft glow of the vacuum tubes, seen through the fine glass side-panel handmade by expert craftsmen, is sure to provide you with deep musical relaxation.
