Transistors
Transistors MP14A are germanium, alloy-type, switching, low frequency, low wattage with p-n-p structure.
Transistors are designed for amplifying of small signals of low frequency, amplifying, switching, application in ferri-transistor cells.
Transistors are produced in metal-glass casing with flexible leads.
Transistor weight, maximum 2g.
