This 1958 Muntz is a four tube super-heterodyne AM radio. “Muntz” is short for Earl William “Madman” Muntz (pictured below) who made millions selling cheap cars, radios and televisions between 1934 and 1985.
When testing the tubes, I noticed someone had subbed in a 50EH5 output tube instead of using the 50C5 as listed on the schematic. When I tried testing the 50EH5, the glass on the bottom of the tube shattered. Luckily, I had a spare 50C5 on hand from my last repair and installed to bring her back within spec of the schematics.
After the two capacitors, one resistor and the new tube were installed, she came to life quickly.
Photos of the dirty insides are posted below along with a couple of videos showing her playing the only AM station I pick up well at my home, WSM 650 AM.
This pink Muntz radio only has four tubes and needed just two capacitors and one resistor replaced to come back to life. I also had to replace the 50C5 output tube but now she’s playing like she should. Now I just need to clean off the 50+ years of dust 😷 . . . . #radiorepair #tuberadio #muntz #muntzman #antiqueradio #vintageradio #oldradio #amradio #wsm #vintageaudio
Here is the pink Muntz radio all back together and playing WSM (the only AM station I can really tune in this part of the house). Couple of things: 1) I love the design behind the knobs, with the gray streaky pattern and 2) I couldn’t figure out how to install the tuning knob so it properly displayed the station and then I noticed a little pink triangle at the top of the dial and I knew then how to fasten correctly. Such fun little details. . . . . #tubesound #tuberadio #muntzaudio #madmanmuntz #antiqueradio #oldradio #vintageradio #vintageaudio #wsm #ifixedit
