This is a list of European Mullard-Philips vacuum tubes and their American equivalents. Most post-war European thermionic valve (vacuum tube) manufacturers have used the Mullard-Philips tube designation naming scheme.
Special quality variants may have the letters "SQ" appended, or the device description letters may be swapped with the numerals (e.g. an E82CC is a special quality version of an ECC82)
Note: Typecode explained above. The part behind a slash ("/") is the RMA/RETMA/EIA equivalent.
Note: Many "C" tubes had 13V/200mA heaters, so apart from 1930s European AC/DC radios, these were also used in 12-Volts car radios: 6
Note: D-type tubes except some rectifiers are directly heated.
