A genuine brand name version of almost any kind of transistor was about 4 Deutschmarks in the 70's. Each one was packaged in its own little paper box. The situation might have been a bit better for the guys who lived in larger cities.


Was it really that bad in Germany? By the late '60's I had
transistors coming out my ears... even built a 30W stereo by 1967 ;-)


Not necessarily if you lived in a big city. If not you had three options: Take a train to a big city (costs money), go to a 2nd tier more local place and risk receiving re-labeled product, or wait until the next bulk waste collection day comes around and develop Eagle's eyes for spotting "high-yield" TV sets. There were some brands we wouldn't touch with a 10ft pole.

I am not complaining at all because this taught us a valuable lesson before even thinking about an engineering career: Make do with what's available. Don't do boutique designs or copy magazine ideas that clearly contain unobtanium parts. Remember all those tunnel diode or UJT oscillators? Plain baloney because no ordinary person could ever lay hands on one. At least not over there. So I did audio stuff with AF239 transistors which is like hauling firewood in a Porsche. But it worked and they were free. Well, except for the band-aids needed after extricating them from tuner boxes but mom paid for those ;-)


I used Motorola RF power transistors for my stereo ;-)


Well, yeah, you worked there :-)

After the original one blew I had a Motorola 6W RF transistor in a 10W FM rig because the 10W edition was too pricey for someone in college. Well, I could have dipped into the beer budget but there are some things man doesn't do.
