Do you happen to have a photo of the top of the transistor? Those old TO-5 packages many times have the standard denomination in the top and left the sides for fabrication date, lot, etc.
Also, from what I have seen, GE used black in some of their early silicon switching transistors. I have several 2N697 that are just like that. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
