For one, it acted like a rectifier ... In essence, the four-layer diode was the first integrated circuit since it did the work of two transistors, two resistors, and a diode -- all in a single ...

First he guaranteed he was working with a DC power source by inserting a small full-wave bridge rectifier ... used some 1978 vintage current limiting diodes designed to pass 2mA each regardless ...

By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display ... The aluminum and the conductive electrolyte are the two capacitor plates.

Under the hood, the 100-watt head comes packing with five 12AX7 preamp tubes, four 6L6 power amp tubes, and two ... rectifiers – which, in turn, toggle between tube and silicon diode rectifier ...
