The amplifier featured five valves and an output of 10 watts - hence '5-10'. Of those valves, one was a full-wave rectifier (an EZ80 or EZ81), one was a pre-amplifier pentode EF86 and one a double-triode ECC83 as phase splitter. The power amplification was handled by a pair of EL84 working in push-pull configuration.
A food pyramid's tip is the smallest part, so the fats and sweets in the top of the Food Pyramid should comprise the smallest percentage of the diet. The foods at the top of the food pyramid should be eaten sparingly because they provide calories, but not much in the way of nutrition.
Mullard Circuits for Audio Amplifiers is a famous book by the Technical Services Department of Mullard Ltd, a British valve manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur constructors as well as by manufacturers as the basis for many ...
Creating an under-500 calorie menu - that a food-loving person would actually enjoy - seemed to be a daunting task at first, but it turned out to be much easier (and tastier) than we had imagined.
There's also the 5:2 diet, where you eat less than 500 calories for two non-consecutive days a week (for men, it’s less than 600 calories) and eat normally for the rest of the time.
The basic gain stage for a valve amplifier is the auto-biased common cathode stage, in which an anode resistor, the valve, and a cathode resistor form a potential divider across the supply rails. The resistance of the valve varies as a function of the voltage on the grid, relative to the voltage on the cathode.
Monday night’s dinner is a quick and easy pasta dish, packed with protein from turkey sausage and lots of vitamins and nutrients from kale, bell peppers and whole-wheat pasta. The whole-wheat ...
It is a sister company to Ashdown Engineering, which makes high-quality, hand-wired, vacuum-tube (or valve in Britain) amplifiers in England. At the end of 2007 it was announced that Dave Green, Matamp's chief engineer, would be joining Hayden full-time as 'Valve Amp Guru'.
