EF 80 Valve

Zoccolo Noval, 9 pin miniature (USA pico-9) B9A Filamento Vf 6.3 Volt / If 0.3 Ampere / Indirect / Specified voltage AND current AC/DC Description Information Hans M. Knoll: The EBF80, which appeared on radios from 1950/51, can already be found with data 8.6.49. PHILIPS had a TV market in France, UK and other countries long before Germany became interesting for Philips for the TV market from the end of 1952. That's why Philips had production and development sites with MULLARD, BRIMAR, CIFTE, etc. long before VALVO. A data sheet from the Netherlands dated November 15, 1949 shows the tubes EF80, EQ80, ECL80, PL81 and PY80 for the TX400-A model. However, we differentiate between tube development and pre-series for circuit and model development from the market launch, which we record (production series on the market).
