 Restoring a 1960 Austrian 7-transistor MW/LW radio. From https://www.abetterpage.com/wt/euro/EumigOkay.html I have several projects that I've not been following through. Here's another one. It's a 1960 transistor radio with the MW and LW bands, which at the time would have had a good coverage of programming in Central Europe. A contemporary review noted the cheap price and the good value for the money.  Now the LW, which is mainly a European band, is practically dead, with the MW dying. If I can't get any actual stations, I have the signal generators. Some notes: -the construction is weirdly complicated, as if the designers had not yet clearly understood that the PCB is for making things sit nice and straight. There's a large number of jumper wires at odd places. The small signal AF part is an absolute traffic jam. I used 1/8W resistors in the rebuild for that part. I could have used them everywhere for the small power rating there is in the set, but the looks woul...

  Itapirkanmaa2 builds a monster power supply: I went back to my old hobby which is old radios. This time around, I decided I need proper testing and other gear. There's quite a bit of material that could be forthcoming on this field. I have accumulated lotsa stuff for "when I have time", but each of us only has some, eventually. So let's begin with getting a proper power supply. Radios of course have one built in, in one way or another, but it may not always be functioning, so having one ready "off-line" is quite useful. I could be buying a ton of cheap Chinese stuff for the power supply, BUT, and it's a really biggie BUT: they would be switching power supplies. Those will by necessity radiate extra radio frequency energy, and the suppression of those emissions may not be very effective, as the proper shielding costs money, which everyone in China would so much like to be saving. Moreover, working on radios, we do not want any of that excess radiation t...
