|Frank's Electron tube Pages|
|This is me in 1998. I was born in 1951 in The Hague. When I was 1 year old, my parents moved to Eindhoven because my dad found a job at Philips. At a very young age I developed interests in anything technical. I opened alarm clocks to see what was inside and that sort of thing. At the age of 6 I discovered radios and other electronic stuff. My neighbor was working with electronics at home and he had a very interesting workroom with lots of electronic instruments and parts. (I think he made his own 'projecting' TV - but I'm not sure)|
|I also discovered that my dads radio (Bantam - see photo with the bantam and my grandfather) was not full of little people, but there where all kind of mysterious things in it. A friend of my dad stopped with his hobby and donated me a few instruments. (I now know that it were receivers/transmitters from the 2nd world war. One of them was a WS38 and I haven't seen the others yet) I took them completely apart (pity) and learned a lot of it. This went on until I was about 11 or 12. From that point on, I did not only take things apart, but I started to do constructive things.|
|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 505K. 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 modifications, that at last it didn't survive. (I remember changing the U-type tubes in to E-types and adding a transformer)|
|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.|
|In the 1970's I changed to transistors. I made poweramps with 2N3055 like transistors. Then there was the Microprocessor. I made my own ÁP system around the 2650 of Signetics. Disadvantage of making your own system is that you also have to write all the software for it, in assembly. Around 1984 I planned to make a new system with the 6809. This was never completed. By then it was much cheaper to buy a system. Because I hated Intellish CPU's, (for those segments etc.) I got me an Atari 1040ST. I taught myself the C language and I had a lot of fun with it. In the 1990's when the PC got 'better' then an Atari (Windows), I bought me a PC.|
|Around 1992 I completely turned to software, until a friend of me started a new hobby: restoration of old Wurlitzer jukeboxes. He sometimes came to me with a defective amplifier. At that time the old times came back (the smell of old tube amps) and I started thinking tubes again. For some time I repaired old amps for several people. But I stopped doing that, because it's not nice repairing the same amps over and over again. I also tell everyone I know that I collect tubes and books about tubes. This is why I already have a lot of nice tubes. I already had a lot of tube data from my early days, because I never threw away a book about tubes.|
I have several old radios: Some Philips radios and a British RGD. I also have a small tube collection. I sometimes visit (radio) flea markets to look for old literature and old tubes.
I still have some fantasies like building a tubetester or a digital clock without semiconductors. As I don't have much time (website...), I will probably never build these things.
And now ... I'm using most of my free time to expand my homepage with tube data. Scanning sheets takes a lot of my time. But I like making this home-page and the many positive reactions prove that it's useful!
Also, I like to 'play' with old electronic equipment using electron tubes.
