“At the age of 10 we moved to Copenhagen for about 2 years. I had some friends there who knew that I liked old radios so regularly someone brought me one. (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 …….”

The tube data resides on several mirror sites in several countries and they are exactly equal, except for the Poland site which additionally has been equipped with a tube search.

“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.”
hobby-electronics.info information site electronics hobby. For beginners or learners taking an electronics course! would be a fun way to start. Electronics Projects page has some projects with a PCB layout for easy building too.

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.”

NIXIE II A Talking NIXIE Alarm Clock! This Nixie Alarm clock will wake you up with a personal wake-up message or sound. A “wav” file stored in EPROM is played using only a few counters and a DA converter.
The µSCOPE – A poormans OscilloScope
“These days this obviously can be done much simpler. The present generation of micro controllers is so powerful that such a videoscope concept can be realized almost completely in software. Recently I obtained a sample of the 12f675. On examination of the datasheet of this small 8 pins micro controller from Microchip, it appeared that the small package contained all the components of a miniature videoscope. In short the µSCOPE project was born, with as main objective the challenge of implementing such a relatively complex task in this small micro controller. The result summarized on this web page is a fully functional (memory)scope that samples the analogue input signal and subsequently displays it on a normal TV”
