37-610 AM Band Dead
#1

This was a total rebuild of a 37-610 Code 121 chassis. Except for the tuner, which had the resistors and paper caps replaced. I was able to calibrate the 470 kc IF and both shortwave bands, but get nothing on AM. I've done a thorough point to point check against the schematic and everything looks OK. The only discrepancy I see is at the AM oscillator coil. (see image) It measures 8 ohms where the schematic shows its value at .8 ohms. Seeing that it has continuity, I wouldn't expect its value to drastically change. Perhaps this is a typo? If not, could it be preventing the signal flow? I only get some static when the tuner cap is turned wide open. I've spent several days trying to find the source of this problem. Where else can I check? I need some expert guidance please.  And thanks in advance!
