Does the 2.49K resistor still measure 2.49K?

My apologizes for the late response, came back from a trip and had a case of covid. The 2.49 resistor measures at around 0.08 now.

I would start by replacing that part and the TL431 on that side as well.

Did you mean the LM431 regulator? I looked at the parts list for the shunt regulator and only saw the LM431 and no TL431.

Yes, they are the same part from different manufacturers.

I just want to confirm that my JC2907AN43 is the same as the PN2907A transistor.
