Transistors are just like Transformers. Only 5 letters difference.
Transistor Building Blocks
Tips/Techniques
Darlington Transistors have Internal Resistors

It's possible, but be aware of what voltage your meter outputs, what is required for conduction, and what resistance to expect.
Gate and Source on a JFET are 'sometimes' interchangeable
I was looking at this data sheet for a repair (nte312): https://www.digikey.com/en/htmldatasheets/production/5439610/0/0/1/nte312 And saw this note at the end. This is discussed in forums online. Stack exchange and eevblog...
