Hello everyone,

Sorry, I'm not good with schematics. Could someone take a look at the schematic attached and please tell me if the values of the double can's capacitors are 12 uF and 3 uF? (#15 on the schematic)  Just want to be sure I am correct before I proceed. 

Thanks
You are correct. Pay attention to how the can is mounted. There's probably a cardboard or paper sleeve between the clamp and the can keeping the can from chassis ground. Any wires attached to the can terminals are B- connections, not chassis ground.
If the 2 section electrolytic can in your radio proves to be as much of a pain as the one in mine was, rather than trying to re-stuff the original you can make a good looking replica. Here is a link to a thread of mine showing the procedure.

Thanks a lot for the advice RodB.  Yes, it does have a paper sleeve between the can and clamp (see attached pic). I’m going to re-stuff the can, so that raises another question. Since it is B - do I wire the negative (-) of the electrolytic to the can and the positive (+) to the terminal just like you would normally? I was planning on drilling a hole and attaching the negative side of the capacitor to the can with a screw and nut.
Thanks Mike. That looks really nice. I’ll try stuffing the original cans first. If that doesn’t work out, I’ll have a plan B now thanks to you.
You can wire the negatives to the can as long as you remount the can with a nonconductive sleeve where the old one was.
Thanks Rod. Appreciate the help.

Hello kedyer,
I will be restoring my Philco maybe this winter and mine also has those same capacitors and yes you can connect the Neg of the electrolytic capacitor to the can it's self !

Thanks Richard. Appreciate all the help and advice.

Best of luck with your restore also,

Hello Keith,
Thank you and hopefuly I can get to the radio with all my other projects on my plate
