The IF transformer is held in by one bolt, under the chassis. Remove the bolt and the transformer can be pulled out from underneath. The resistor in question is on the very top of the transformer.

I have found the best way to replace the resistor is to clip the leads right at the resistor body and then attach the new resistor to the stubs. I tried unsoldering one of those resistors from the transformer once...and ruined the transformer. Icon_redface

If your 80 now works to your liking, it is probably best to leave the resistor alone. In my experience, replacing it with a 2 meg resistor really helped the set's sensitivity.

Oh, and congratulations on finding the problem! Icon_clap Icon_thumbup
