(See my picture at the main page) Among them was the Bang & Olufsen – Grand Prix 48 K (photo). I liked this radio so much that I wanted to make it work again. There was not much wrong so I got it working. Later when we were back in Eindhoven, I made so many …….”

“Back in Eindhoven, there where the 60’s. Radio Luxembourg on my B&O etc. I got interest in guitars and amplifiers. I built several Amps. My first amp was something with the EF11 and the EL3. I also built a copy of the Philips EL6431 Amplifier. (That’s where the output transformer of my B&O radio went) In Eindhoven there was a repair shop called ‘De Radiodokter’. He had some old TV chassis in the display for 5 guilders each. When I had saved enough money, I bought some. Then when I was about 16 I made my first really working TV from these parts.”

The Course – “We start with a few lessons about voltage, current en resistance. Next, we’ll discuss power dissipation and capacitors, diodes and transistors. We now have enough knowlegdge to build a simple power supply. And after a few lessons about differential amplifiers and operational amplifiers, we are even able to design and build a professional lab power supply.”
