THis is an in-house number (inventory control).
The whole intention is to hide the identity of the device being used.
It reads 1969- lot# 526 design.

SJE, SRF etc are all examples of controlled devices.
Same story as above, the information will not be released...
You are out of luck, try generic power devices once you determine
if it's PNP or NPN.
