A window through time – Sylvania’s first radio tube factory

The first Sylvania radio tube factory in Emporium, Pennsylvania

From this small factory at Emporium, Pa. the first Sylvania radio tubes were shipped on Thanksgiving Eve, 1924. It was built in 1906, by Sylvania’s parent company, the Novelty Incandescent Lamp Co. If you own a PC-2A compressor or any of the other small Effectrode pedals fitted with subminiature tubes then you have a tiny piece of American (Sylvanian!) history beneath your feet. Although the subminiature tubes utilised in our pedals didn’t originate from this factory, they were made in a larger, more “modern” facility built in 1929, also located in Emporium. You can find out more in this old Sylvania Newsletter article.
