discrete opamp help
I joined to see if anyone can assist.
I have found a lot of General Electric discrete opamp modules. They have 12 pins but none of them are labeled on the case. The case is blue and labeled GE 231E356G2 68L5165. I am guessing the second set of numbers is a date code so probably 1968.

I have looked around the internet for online manuals but nothing related to this part number. Anyone have the GE Semiconductor Manual from late 60s early 70s that these would have been listed in? I can buy one but they are $8 and I don't want to order one and find out the part is not in it.

Thanks in advance
