  • TUBE AMPLIFIERS are devices whose technology was developed in the middle of the last century to amplify sound. They not only improve sound transmission, but also allow you to achieve a natural and transparent sound. This effect is achieved due to such a unique element as a vacuum tubes It has a wide sound amplification band and a high level of linearity, and also makes it possible to implement in practice the shortest possible audio path. Since its inception, tube amplifiers have had their ups and downs. So, in the post-war period, these devices were used everywhere. However, at some point, innovative transistor amplifiers loomed on the horizon, which intercepted the thread of the championship, and the lamp equipment was "pushed" into the background. Regain your leading position tube amplifiers only succeeded in the late 80s, thanks to the advent of higher technologies in production electronic components. It was at this time that many users were able to appreciate the great sound that provided reproducing devices with a tube amplifier. Components from global brands By individual order, the amplifier can be equipped (partially or completely) with components, produced by world sound manufacturers. Our company has developed several options for housings, which allows us to produce the same products. in different designs. All amplifiers use one- or two-stage anode voltage supply (delay 30 sec.), necessary for the normal exit of the circuit into the mode. The circuitry used in the amplifiers is both well-known and original developed by the company's employees. Creation of Tube Amplifiers by High-End concept designed for a wide range of audiences.

Vacuum tube single -ended tube  amplifier GU-80The amplifier combines two separate modules – for the left and for the right stereo channels.Each module implements an amplifier stage built using a vacuum tube 6Э6П-ЕВ ( e810cc  , D3a )  and a 300V voltage converter, which in turn supplies operational voltage to the output tube GU-80.The input of every module is routed to its RCA input connector, and its volume control. The input sensitivity of the amplifier is sufficient to directly accept the input signal from either a turntable or a pre-amplifier.The rear panel of the amplifier includes two connectors. They are used to set supply current to the output vacuum tube (240mA). To control the output current, a multi-turn potentiometer is accessible from the rear panel. To adjust the current, a small flat screwdriver should be inserted into an access slot in the rear panel.The built-in power supply provides the normal operation from the line voltage in the range of 170 to 265VAC. The power supply has an overvoltage detection and protection: if the line voltage exceeds the nominal value, the protection circuitry automatically shuts down the amplifier.The wide range of the line voltages is made possible by use of a proprietary microcontroller-based circuitry, which monitors the line voltage, and automatically selects the proper tap of the power transformer. Thus, the power transformer configuration is automatically aligned with the input AC voltage, assuring its optimal operation.Specifications:Configuration:  Single module - mono block Nominal power 100W at 5 Ohm load.Frequency range 16Hz to 50kHz.Output impedance 0.5 OhmInput impedance (L-type regulator) – 18 to 32kOhm, adjusted by regulatorPower consumption – 400WLine voltage 170 to 265 VAC430 х 500 х 320 Dimetions (mm)Weight - 46 (kg)Warnings!!!1. Vacuum tube GU-80 is hot when operated, keep out of reach of children and pets! Avoid a direct contact with skin!2. Vacuum tube GU-80 operates at a high voltage, keep out of reach of children and pets! Avoid a direct contact with skin!3. Do not replace vacuum tubes during operation! To replace a vacuum tube, power down the amplifier, and wait a few minutes for the tube to cool down.4. Do not power up the amplifier when vacuum tubes are not properly installed! It would cause damage of the amplifier circuitry...
