a real challange?

See below.

there is a point E, that they suggest feeding in a signal into when alignment it REALLY bad, it's on the far end of the mixer coil stack in the tuner, and feeds into 1st IF.

This sounds reasonable to try.

I have found very few resistors bad above 1k ( just a few), but so far EVERY ONE, of the 150 ohms has been bad by 60%-190%, and there are 3 in the tuner
but I really dread pulling it out to replace them.

You can measure B+ plate resistors in the tuner between tube socket plate pins to some other B+ point accessible outside the tuner. If there's more than one in series simply add up their values. Then you will know instead of wondering. Study the schematic and you may be able to sniff out others using the same method.
