EFP60 - Secondary Emission Amplifier
Almost certainly Philips EFP60 was the first high-frequency amplifier based upon the
secondary emission effect. This article, dated August 1939, with the contribution of
British Mullard on the Journal of Scientific Instruments allows to date the
announcement of the tube just few days before WWII began in Europe. It was
probably intended for applications as VHF amplifier in then promising television
field. All the available resources were moved to military productions and both
television and EFP60 had to wait until the end of the war. In the meantime the
secondary emission effect was exploited in America by RCA to design the giant
acorn tubes, 1630 and its prototype R-1790, as RF front-end in early SCR-270 VHF
radar sets. But the war efforts generated countless devices, capable of handling any
signals, and EFP60 was confined to few niche markets in the instrumentation field.
The basic Philips production was marketed worldwide with the various brands related
to the mother firm. The above sample, ‘Made in Holland’, was badged as Amperex.
