Dave, don't be in a hurry to randomly replace parts without localizing the actual problem. 

As mentioned by others it appears that all the paper caps in the bakelite blocks have been replaced. It seems that the detector and audio stage are working properly, so why would you consider blindly changing parts without investigating further? A systematic, logical approach to troubleshooting produces better results and minimizes the risk of inadvertently creating new problems which did not exist before

Concentrate your efforts on checking the antenna and oscillator coils for open windings, and check the circuitry around the miixer/oscillator tube ( 1st detector ) as it appears that this is where your problem originates.
