HHHHH chrome version >> K4040 HHHHH black version >> K4040B STEREO VALVE AMPLIFIER Now everybody can enjoy that sublime "valve sound". The sound of valves cannot be surpassed, neither by transistors nor FETs. In the development process, special attention was given to the housing so that the expensive valves are displayed in a visually attractive manner. The most vulnerable point of a valve amplifier are the output transformers; that's why we use ultra-linear and overrated output transformers (toroidal) to guarantee a rich bass response. To extend the life of the precious valves, the amplifier has a switch-on delay so that the high voltage is switched on when the valves are warmed up. • output power: 2 x 90Wrms music power for loads of 4 or 8 ohm • power bandwidth: 15Hz - 40kHz (-3dB ref. 50W) • frequency range: 8Hz - 80kHz (-3dB ref. 1W) • harmonic distortion: 0.08% (1kHz / 1W) / 0.7% (1kHz / 90W) • signal-to-noise ratio: > 105dB (A-weighted ref. 90W) • channel separation: > 75dB (ref. 90W) • input impedance: 34Kohm • input sensitivity: 1Vrms at 95W • damping factor: > 10 (100Hz) • weight: 23.46Kg • dimensions: 425 x 130 x 350mm / 16.7 x 5.1 x 13.8"

H >> K4001 7 W MONO AUDIO AMPLIFIER This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4 ohms. The IC is fully protected against overheating and short circuits. A conventional direct current is sufficient as power supply.

H >> K4003 2 x 30 W AUDIO POWER AMPLIFIER This small amplifier is constructed with the TDA2616 IC, with a maximum supply capability of 2 x 15Wrms (4 ohm) of 2 x 10Wrms (8 ohm). The IC is protected against overheating and short circuits. Additional rectifier and smoothing filter are unnecessary because alternating current can be connected directly with the unit.

 HH >> K1803 UNIVERSAL MONO PRE-AMPLIFIER This kit was developed as pre-module for a number of audio applications where the input signal is too weak. Applications as a microphone pre-amplifier or for level correction.
