Hello everyone. This is my first post here.
I've had a Philco 46-350 (a common model I hear) for about 10 years now and the other day I was looking at it and decided I was finally ready to restore it. 10 years ago, my grandpa gave this to me and I was just a teenage kid. Back then, I replaced the cord on it because the old one was cracked and I figured it would fix it. I was wrong. The thing still didn't turn on. Back then, I remember looking for resources on what would be wrong with it and how to fix it, however I remember the only thing I could find was a couple of websites that provided services on fixing radios so I decided to give up and shelve it.
Fast forward 10 years later...
The internet has WAY more resources for fixing radios now and I've decided to finally tackle this project again. I've read a lot of resources on fixing radios and found the schematic for my model and feel pretty confident about this project. I've decided to replace all of the non-electrolytic wax capacitors and the "can" electrolytic capacitor. I've already started to order supplies for it. Now, I've got a little bit of experience fixing antique fans but this is my first radio, thus I may have a few questions along the way. Thus my first question is this:
My "can" multi electrolytic capacitor looks like it exploded. The middle was blown out of it and looked like it was bulging outwards. What would cause it to do this? The reason I ask this is because I obviously don't want to put another one in there and have it explode again if it is caused by some issue other than the can itself.
Thanks,
-Josh
