This new A-19 is the successor of our famous A-18. The fet power transistors now are driven by a bipolar drive circuit with a mute possibility.

The specifications are somewhat better. The bandwidth now is wider, distortion is lower and the damping factor is increased.

The new D-702 is the successor of our famous D-402 design. The major difference with the former D-402 is the larger power and the bigger damping factor.

This module can be switched as a 2 x 12 Watt power amplifier or, when switched into a "bridge"configuration it delivers 20 Watt mono. The module is universal and could also be used in a surround set up.

The module should be supplied vwith an adequate power supply and a relatively small cabinet.

The price of the stereo module is 50 Euro.

This is a mono tube power amplifier based on the former ideas of Jean Hiraga, Menno Spijker, Menno van der Veen and Jacco Dekkers. The amplifier has a frequency range from 15 Hz to 100.000 Hz and delivers 12 Watt into 8 Ohm. If there interest for it we will also develop a 40 Watt model.

In development!
