Emperor Radio Tubes
Perhaps based in New York, where their boxes were printed. No other info is known.
Last seen: no advertising found
The Emperor brand name was well enough known to be found on compiled lists of 201 brand names, but I had never seen any actual evidence of their existence.
The example in my collection was purchased by the seller at a HAM swap meet in Georgia. It appears to be in first state condition, and helps us understand why we never see this tube found loose. Inside the carton, an inserted, unbranded RCA Radiotron 01A ST shouldered tube, in a one-piece corrugated cardboard insert. Nothing else. Emporer tubes was surely produced on a shoe-string.
No advertising has been found, though we can date the tube using the Dowd RCA factory marks charts.
A very difficult box to find in good condition, due to it's largely white surface. Depression era boxes used cheaper box builds than the earlier kraft boxes, and white printing was largely new to cardboard designs.
