Confirmation of a no-brainer, Please!
#2

Ok- I swapped in a temporary patch- I snipped out the wrong resistor, and in its place substituted 3- 100k's and a 33k, with a total resistance of 339(?)k ohms, where it should be 330k. My estimated window is 297-363k ohms, so I should be ok. I now get squak. No stations yet, but that is most likely because everything is out of alignment now, having muckered about with everything I could see to try to get anything out of it. And the good news is, the squakies do very nicely with tuning adjustment, and the volume gets loud and soft now- a marked improvement over what was happening.

I will now attempt to divine the RF generator and its use to align everything. Pay no attention to the man behind the curtain...

This is only on the AM side of the house: I have no SW noise at all. First I want something going, then I'll worry about the details...

Any tips, hints, gladly accepted!
Thanks!
Scott
