It is posible that the problem is not even related to the capacitor change. I can't tell you how many times I have had a problem crop up, completely unrelated to the part I'm working on. Here is a couple of quick tests.With your finger, touch the grid cap of the 2nd detector tube. You should hear a hum. If not the problem is in the output section or the power supply. Next tune the radio to the low end of the dial, say about 600 KC. Your radio has an IF frequency of 470 KC, so tune another radio to 1070KC and see if you can hear a squeal or howl. You may need to rock one of the dials a little. If there isn't, the oscillator isn't working.
