Hello,
I pulled out two transistors which I think are defective from an electronic balance but having trouble identifying their correct specifications. The markings are N1117 and N1212. In my opinion the full part number should be 2N1117 and 2N1212 (please correct me if I'm wrong).
Anyhow, I have looked at many datasheets from several websites for 2N1117 & 2N1212 but the package styles indicated on these datasheets are totally different from the actual parts I pulled out. 2N1117 datasheets show a TO-39 style and 2N1212 a TO-61 style. The electronic balance was purchased in the early 90s' so I'm guessing many of the electronic components are now obsolete.
I'm trying to get substitutes but cannot do so until I'm able to correctly identify the original parts and pinouts. Would be appreciative if someone from this forum can provide some details on these parts.
Below is a picture of these parts for reference:

Thank you in advance.
