The 1960's GE Musaphonic

[TUD1]

I got this very nice sounding tube radio at The World's Longest Yardsale the summer before 7th grade (Years ago...) for only $1. It works good, but is tempermental. Sometimes, if it is on longer than 15-25 minutes, it will start popping, cutting out, and will ultimately go silent. I was listening to it tonight on AM, and the song "Cats in a Cradle" came on, and it made it through the song, then started cutting out. The model No. is unknown, as the sticker was replaced by a hand drawn schematic for the tubes.
