After initial recapping of this Ward Airline radio, it exhibited signs of silver mica disease. Attempting my first repair on an IF Transformer, I have some questions which I hope you can help me with 1. The schematic shows two mica caps but only gives one overall value 250mmf which covers both. How can I determine the individual values I should use for my two replacement caps? 120 pf each? 2. Removing the internal componets to get to the original mica caps, I made a rooky mistake and broke one of the two fine wires that run up the side. The wire gage is very fine. Should I solder a replacement length of wire I have available (24 Ga) or is there another way to properly repair this? Thanks and I hope you can help me. |

Just by trial and error: I would install two 120 caps and see if I can tune an IF maximum. If that fails, two 250 caps should do the job. Good luck!
