Mullard
The Mullard Radio Valve Company, founded in 1920 by captain Stanley R. Mullard, has been the leading pipe manufacturer in the UK. Co-founder of the BBC and producer of one of the most famous pentodes the 'EL34' a Philips invented and patented process to counteract the unwanted secondary emission of electrons with the help of a third grid (the supressor grid). Philips took over all shares in Mullard in 1927 and built a factory for the manufacture of radios in the thirties alongside a Mullard factory in Mitchum. The best known tube is of course the EL34 introduced in 1949 by Philips manufactured with the aforementioned patented surpressor grid so that together with the other four electrodes namely the Cathode, the Anode, the Control grid, the Screen grid a so-called pentode tube arose, pentode derived of Ancient Greek Penta which means five.
Mullard was taken over in 2007 by the American New Sensor and produces under this name several Mullard classics including of course the EL84 which we have standard in our product range in matched sets of two and four pieces.
