When did Philips STOP manufacturing the OC75 transistor?

[mordechai]

Anybody know the date range of its production run?

Hi
The production run was probably short at each factory. Maybe only a few months. (Mullard in GrBrit and maybe Holland, Valvo elsewhere, ?? for the CV7003).
They were sold for several years (1960 to about 1969 ??).
From memory, one site said Mullard GB (parent company was Philips) did a run of them in 1960. No idea whether they ever did another.
