LCD Panel Meter Kit

No Longer Available
A digital meter is a lot easier to read and much more precise than its analogue equivalent. Moreover, this panel meter is comparable to an analogue one because a regulated power supply is no longer needed ; in many cases, an ordinary 9V battery is sufficient. As a result of the compact meter construction, there will never be problems finding a place to install it. It can easily be combined with an adapter circuit or sensor
Dimensions: 50 x 72mm (PCB)
Power Supply: 8-15Vdc or 9V Battery

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.
