Philco 37-690 Restoration
#14

Good morning, I took a vacation day off work today so I can do some more work on my 37-690. I got the power unit all recapped and decided to test it out and the radio works quite well other than a lot of crackling/popping noises in the audio which I suspect the large candohm being the culprit (I did order resistors to replace the 2240/3000 ohm sections)This radio is quite loud and the automatic bass control is working as well as the high frequency speakers. I checked the dial calibration according to the service bulletin and noticed all bands except for band 2 are slightly off but that shouldn't be an issue to realign the other 4 bands----band 2 dial accuracy is excellent. I tested the magnetic tuning operation and it works great. Hopefully when I replace the 2 resistors in the candohm unit the crackling will disappear. I'll have pics of the setup as soon as my cell phone is done charging.  Ken
