Completly useless! But cute
A freebe at the antique radio club meeting condition unknown. I wanted to clean it up take a peek and then return it to the club to donate for the auction. Appeared used and obviously had been apart by the usual tell-tale signs on this kind of chassis where the face inserts into the box interior. Yet it still has the remnants of the store-tag hanging from the handle. The string is very delicate and parted; had to tape the tag back to it. Radio Museum has a picture of the tag and it was $34.50. Not especially cheap in 1953! Serial number 143938. The included manual is dated 1953.
Even though it had been opened everything appeared original. Looked for a bit it would come up and work but the electrolytic, C10/11 got unhappy. It did test really leaky. The 3 paper caps, C9 and C12/13, also tested really leaky. And the filter R7 tested high. By appearance it looked more like a 30's part than 'modern' carbon comp. Since this is not intended or expected to be used the two line caps, C12/13 were left out. C10/11 (10uF) was replaced with a couple Elna 22uF pulled from a previous project.
The operating manual and schematic are all over the web. Check Radio Museum. I did annotate a couple voltages that might be useful to someone.
And of course; the whole reason it's cool. Tube Glow!
