[Hammarlund] HQ-145 misprint or what?

[GARY BROWN]

I have an HQ-145 on the bench that belongs to a friend of mine. His complaint was it was never a good receiver. He has had it from day one but just recently brought it out of the closet after all these years.
    Here is the problem. The original manual says a 6.8 meg resistor from pin #6 to pin #7 on V-4 (6BA6), IF amp. I am looking at this resistor and its across pin #1 to pin #7. BUT, get this, The original diagram shows a 2.2k (R-44) from pin #1 of this same tube where the one I have is 470K. Now, the resistor from Pin #6 shows 470k on the diagram but mine is 2.2k. Looks like these resistors were reversed for some reason. Doesn't look like any one has ever touched them. As for the rest of the circuits, its the same as the original manual diagram.
Now, my question. Were there production changes made to the IF amp? If not, do you think these resistors were wired wrong at the factory.
