With all of my aches, pains and health issues of late, I
feel like an
antique. But while I don't consider this similarly-aged radio to be an "antique" per se, I have a Grundig 2420-U tabletop radio. This was built circa 1964.
This photo was taken before I cleaned it up. My buddy let me have this radio--it was his grandmother's, and he had me take it when he and his sisters were cleaning out his parents' house. His grandmother used to play this radio constantly, and it was always on anytime they would go over to her house.
Normally I would have passed this up but when I was a kid, my uncle had this exact same model in their kitchen, and I used to play with it when I went over there. Eventually it ended up in the warehouse at the office, where it plugged away for nine hours a day non-stop and kept on working, without a tube change. Yep, this 1964-built monstrosity has tubes. It even has a "magic eye" to the left of the volume control to help with tuning. It has three bands--AM ("BC"), FM, and shortwave.
In some design quirk, the calibrations on the dial run high to low, unlike the low to high like we are used to. Note 88 MHz FM is on the right, and 108 MHz is on the left. I remember once playing with the shortwave band on my uncle's radio, and presumably came across a Romanian broadcast that sounded like it was a polka, but played while the musicians were on speed. 😁
It has a "PU" button. It is not for the Pepe LePew station; it stands for "pick-up," AKA the pick-up (cartridge) of a record player. Or essentially, a line-level input, as those old crystal cartridges were a high enough output to use into line inputs. The input is a 5-pin DIN, and I found an adapter online where I was able to plug a Chromecast Audio puck into it and for a brief while it sounded quite good.
Sadly it is in need of some electronic work, as the sound is kind of weak now. I won't touch the capacitors in the tuner section, but I think all the caps in the audio circuit need replacement. The tubes are probably good. I did try the Telefunken EL84 in another amp I had and it worked perfectly. The magic-eye tube is weak so I may try to source a new one of those. It's a cool unit and with the extra input, it can be quite useful. If reception isn't harmed, I might tuck the Chromecast Audio puck inside and offer it as a cool party trick for this nearly 60 year old radio.
-- but... this and that.
. It does have a product detector for SSB, though, and a line-level output for taping or to connect to a hifi.
