Stereo Valve Amplifier/Chrome Kit K4040

  Constructional Kit: Professional

No Longer Available

For most of us a high power valve amplifier is unaffordable. This kit changes that, so that 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.
Dimensions: 425 x 130 x 350mm
Power Supply: 230Vac

Video and RGB Converter/Processor Kit K4600

No Longer Available
To process a PAL colour video signal it first has to be converted back into the original Red, Green and Blue signals. This allows the colours to be adjusted separately along with the colour intensity, brightness and contrast. Once processed the signal can be converted back into a PAL video signal. The user can choose PAL video or RGB output. In addition space is provided on the PCB for a UHF modulator ( type RFMOD) so you can use the antenna input of your TV or video. An SVHS input signal can also be connected.

Light Computer Kit K5201

  Constructional Kit: Average
No Longer Available
Sixteen different programs and seven outputs make this light computer a unique showpiece. This kit can find applications in party lighting, discotheques, advertisement lighting, signalling, etc. To be able to view the programs directly, each output is provided with a LED. The complete circuit can be installed so that all operations and LEDs are available from the front panel. To enhance the spectacle further, an unlimited number of circuits can be connected together to work synchronously. Moreover, two programs are provided which are specially adapted to operate two light computers in cascade.
