Check http://www.pauls-roehren.de/roehren/...CodeListAB.pdf to see if there are Philips factory codes on the base of the tube. Philips was the owner of various brands like Mullard, Valvo, Dario, Adzam, Sylvania. Besides this, valves were sold OEM to other companies. There were Dumont EL34's on Ebay that had a Philips factory code. Andre |

AFAIK, the DuMont company itself (like Zenith) only made CRTs, and never made recieving tubes. DuMont marketed relabelled tubes from numerous sources. -- Ned Carlson www.tubezone.net South Side of Chicago,IL USA 2/21/2006 4:24:35 AM |

And
Philips owned Sylvania? I know they do now, or the remains thereof. But when the Philadelphia and upstate PA tube factories were still open? Peter Wieck Wyncote, PA |
