TUBE TH 576

GENERAL DESCRIPTION


photo TH576 The TH 576 is a ceramic-metal tetrode of coaxial structure, employing Hypervapotron anode cooling, designed for use in AF and RF amplifiers of frequencies up to 50 MHz. This tube brings increased efficiency to medium- and short-wave transmitters. Moreover, the TH 576's Pyrobloc grids result in highly stable operating characteristics. The anode cooling technique guarantees enhanced safety margins with respect to the operating point.
The 576 delivers up to 550 kW in SW, with a high gain and a high efficiency.
