Hello Philco Gurus,

This is my first post here, in addition to my first radio restoration! Of course, it is a Philco, a 610 tombstone. I heard that if you have a problem or question, this is the place to come.

I am very new to electronics and restoration, so please bare with me at what might seem elementary questions for you veterans.

OK, here goes. My radio hums (big suprise huh?). I replaced all the paper capacitors last night. Everything checked out fine with my work. I was ready to replace the three "Can" electrolytics when I hit a road block.

Here is the schematic I have been using:

http://www.nostalgiaair.org/PagesByModel...013797.pdf

The three caps are:
Schematic #41 16-uf Part No. 30-2118
Schematic #56 8-uf Part No. 30-2025
Schematic #54 8-uf Part No. 30-2025

I have all of the correct value elecrolytic replacements I believe. 3 new caps in all, they are all axial type (2) 8 uf caps and (1) 16 uf cap.

This is what I am unsure of:
I have attached a few photos. Hopefully they post, if not please paste the link into your browser. The first is of the chasis top, second is of the #41 16-uf cap. underneath, the second is of both the #41 and #56 caps underneath.

Before I start my questions, I do know that I need to disconnect the caps.

Okay, my question are the following. In pic number 2 (#41 cap), why is there 2 terminals? There is nothing in the schematic that says it has 2 caps inside the can. There is also nothing in the schematic that tells me the (+) or (-). I noticed that the cap. is insulated from the chasis. Does this mean that the terminal on the outer rim is the ground? That being said, do I solder the (+) lead of the new cap to the wire leads that were connected to the center downrod and the (-) lead of the new cap to the wire leads that were connected to the terminal on the outer rim? I am confused and don't want to destroy this beauty!?!?!

Secondly, in the third pic of both caps. On cap #56, do I solder the positive lead of the new cap to the wire leads that were connected to the downrod? There is only one terminal on this cap. I assume this cap is grounded by the chasis correct? So where do I solder the (-) lead if the chasis is the ground (I do not know where to solder the (-) ground lead on the new cap. if the chasis is the ground on the old cap...please help). I know this last question is elementary, but please bare with me.

Any help would be greatly appreciated.

Thanks in advance!
