PP3/250, MAZDA, ST ENVELOPE, AC044, PX4

£120.00

This ST shaped example of Mazda's iteration of the classic PX4 shows good emission with:-

Ia = 30 mA

gm = 3.7 mA/V

Etched markings on the top dome of the envelope are feint and the envelope is tight to the black base. Base pins show some surface corrosion which should respond well to cleaning further.
