I have attached a rough schematic of the front end area of a Hallicrafters SX-17. The capacitor ID is C47, C49 and C50. All 3 are .05uF and I believe they are bypass capacitors. I have been replacing these wax caps and have all of them replaced with new except these three which are virtually inaccessible. Only one end is accessible, the other is fed through the chassis below the main tuning cap and cannot be reached let alone replaced. My question: I am doing an RF alignment and am having difficulty in aligning the main dial with the actual received signal on a few of the 6 bands available. I suspect these caps if they have turned into resistors are affecting my efforts to calibrate the dial with the actual frequency. What are these caps doing in the circuit and could the be affecting or hindering my attempts to get the dial in line with the injected signal? What if I just snip them out of the circuit ? Circuit diagram, you may need to blow it up, they are at the cold end of the series coils.
