There is a couple of things you can do that don't require any test equipment. First, touch the center terminal of the volume control. You should hear a 60 cycle hum. If you hear the hum, you have proven that the output section and the power supply are working. Next, place a working radio next to your 42-365. with both radios turned on, tune the 42-365 to about 1000, tune the working radio to about 1455. Now, rock the dial on ether radio. You should hear a rushing sound or possibly a whistle coming from the working radio as it picks up the local oscillator of the 42-365. If you haven't already, double check all your work. Check the part values against the schematic and make sure each part that has been replaced is connected to the proper terminals. Make sure your solder connections are good. Take voltage measurements on all tubes and compare them to the service information.
