Re-tested the resistances after disconnecting the microphone. Upon turning on power

Yeah, no. Those resistances you measure with the power OFF.

It helps to know one's tools and how to employ them... Poking around semi-randomly is not exactly the most constructive and/or productive way to go about things.

I'll just put Ian's article here in case it helps.....
maybe knowing some values of things like .3mA etc... can help sort stuff.....

Thanks @scott2000

Thanks for pointing me to Mr Elliot's. Very practical guidance in there.
