Description
The PT is a series of glazed wire-wound potentiometers, made to STAS 9288-79 for professional electronic circuits [1]. The Agenda radioelectronistului (2nd edition, 1989) lists six sizes, PT-16 to PT-160, rated 16 to 160 W, from 10 Ω to 47 kΩ (E6 and E12 series), with limit voltages of 450–2000 V [1].
The Agenda radioelectronistului names IPEE Electro-Argeș of Curtea de Argeș and IIS Electronica of Bucharest as the producers of the potentiometers in its section on potentiometers made in Romania, in both editions, without saying which works made which type; they are listed here under Electronica [3][4].
The book does not explain the codes [1]. The 1st edition (1983) gives the same data [2].
Dimensions in mm (fig. 17.7): maximum diameter Dmax and maximum height Hmax from the table; the table also gives a dimension Amax, which is not marked in the drawing of the 2nd edition (the 1st edition marks it in fig. 3.2.7); shaft Ø 6, threaded bush M10 [1][2].
