These valves are a new variant of the legendary 6550 \/ KT88 power valves. For more than half a century, these classic valves have been the foundation of numerous of high quality amplifiers and surely, they will continue to serve as one of the premium choices among manufactures of high-power valve amplifiers.\u003c\/p\u003e\n\u003cp\u003eHowever, nowadays KT120 is the most powerful dedicated audio tube in production. In comparison with the KT88, nearly 30% more power can be drawn from these impressive valves. With a plate dissipation rating of 60W, a pair of KT120 tubes in push-pull configuration can deliver nearly 200W of audio power. When used in circuit designs of more modest power outputs, the KT120 can deliver incredible quantity of headroom and dynamic without overloading.\u003c\/p\u003e\n\u003cp\u003eWhen output powers of more than 50W are going to be provided from a power amplifier, the input and driver circuits of the amplifier are confronted with a dramatic increase of current needed to supply the power devices of the amplifier. This is a reality regardless if the amplifier is based on bipolar transistors, Fets, or vacuum tubes technology, and no matter if single high power output devices are used for the design or if the amplifier employs multiple low power devices in a parallel configuration.\u003c\/p\u003e\n\u003cp\u003eEven though Fets-semiconductors and audio valves in theory are voltage controlled devices, these also require relatively low impedance driver circuitry with current capability, partly due to the increase of input capacities and partly due to the often neglected fact that also audio valves are drawing current through their input terminals.\u003c\/p\u003eTo prevent excessive loading of the amplifying stages of the amplifier, CTA506 employs efficient buffer circuitries as a method of partitioning the load from the amplifying valves. The buffers are current amplifiers with very low distortion and they do not amplify the signal, they only make it stronger. Another benefit from the use of buffer circuitries is that they allow low impedance DC-coupling between the driver and power valves of the CTA506.\u003cbr\u003e\u003cbr\u003e\n\u003cp\u003eThe CTA506 push pull output stages consists of a pair of marched KT120 in fixed ultra-linear configuration, giving the low distortion of triodes combined with the power of tetrode valves.

Under dynamic conditions this current feedback power plant will deliver several times its rated power - enough to drive almost any loudspeaker.\u003cbr\u003e\u003cbr\u003e\n\nThe CSA150 provides four digital inputs, five analogue inputs and a 150 Watt per channel power amplifier. It borrows its basis circuitry from the CSA100. However, to increase power and maximize performance we have upgraded the power supply with a larger toroidal transformer and a separate fully regulated power supply for the power amplifier driver stages.\u003cbr\u003e\u003cbr\u003e\n\nFurthermore, the heat zinc area has been increased and the chassis resized in order to accommodate the additional hardware.\u003cbr\u003e\u003cbr\u003e\n\n\n\n\u003ch3\u003eInside the CSA150:\u003c\/h3\u003e\n• Employing the Copland double triode gain stage with MOS-FET buffering ensuring a tight interface between the tube and the solid-state parts of the amplifier.\u003cbr\u003e\n\n\n• Immunity to mains fluctuations, load demands and noise interference by use of wide bandwidth power supply regulation, not only for the low-level stages of the amplifier, but also by active regulation of the power amplifier driver stages.\u003cbr\u003e\n\n\n\n• D\/A converter with multiple S\/PDIF inputs, PCM, and DSD capabilities using the ES9018 Reference 32-bit DAC in quad-mono configuration, 8 mono to 2 stereo configurations.\u003cbr\u003e\n\n\n\n• Besides the digital coax and optical inputs an additional Bluetooth aptX module makes airborne sources available in HD quality.\u003cbr\u003e\n\n\n\n• RCA inputs as well as balanced XLR.

Amplifiers are also products for everyday use. Some successfully deviate from the conventional, they remind us of the strive for perfection – a human virtue we like to recognize and being close to.\u003cbr\u003e\u003cbr\u003e\n\n\nThere is a distinctive mood of luxurious puritanism to be found in the appearance of most Copland amplifiers. However, with the CTA407 tube amplifier we have compromised simplicity, introducing a fair deal of electronics supporting the audio stages of the amplifier.\u003cbr\u003e\u003cbr\u003e\n\n\nThe forty LED diodes on the front panel (10 for each tube) are the visual part of the CTA407 tube bias and diagnostic system. And yes, the LEDs can be turned off if you don’t want to read the status of your power tubes on the fly.\u003cbr\u003e\u003cbr\u003e\n\n\nThe CTA407 will automatically adjust for any tube in the 6550\/KT88\/KT120\/KT150 family. The CTA407 servo system is not only a lossless automatization of the bias adjustment – it is an integrated part of the CTA407 internal high pass filtering, closely matched to the transfer function of the amplifying circuitry and a vast improvement to the overall fidelity of the amplifier.\u003cbr\u003e\u003cbr\u003e\n\n\nThe CTA407 employs five line-level inputs including a tape monitor loop and a built-in RIAA phono circuit accommodating moving magnet, as well as high output moving coil cartridges. It is a development of the CTA405 amplifier, an object of desire for audiophiles worldwide since its launch more than a decade ago.\nThe push pull output stages consist of a pair of matched power tubes in fixed ultra linear configuration, providing the low distortion of triodes and the power of tetrode valves. A pair of 6550 or KT-family tubes in push-pull configuration can deliver more than 100W of audio power. Moderating the power output, the CTA407 delivers 2x50W in high biased class A\/AB mode. In practice, this means that the amplifier can deliver most its power in class A state.\u003cbr\u003e\u003cbr\u003e\n\n\nDue to the quality of the output transformers, superb linearity is achieved before feedback is employed, reducing the requirements for internal lag compensation networks, and ensuring high stability after the 18dB negative feedback loop is closed.\u003cbr\u003e\u003cbr\u003e\n\n\nThe CTA407 can provide an extraordinarily accurate reproduction of music without tendency towards listening fatigue, featuring strong dynamics and a wide flexibility in the choice of speakers. The vanishing low perceived noise from the amplifier itself is a bliss, especially for owners of high efficiency speaker systems.\u003cbr\u003e\u003cbr\u003e\n\n\nThe CTA407 employs motor driven volume control and can be fully controlled by the Copland RC102A remote control unit.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\n\n\u003ch3\u003eCTA407 Specifications:\u003c\/h3\u003e\n\nTubes: 6550\/KT88: 4pcs. 12BH7: 2pcs.
