Philco 38-7CS Restoration
#1

Hi Guys,

I need a little help with my restoration on a 38-7cs. 

I need clarification on the connections on the volume pot. There are four connections on the pot. On top there are three and then there is one on the bottom side. For the pots on top, the middle one is the wiper on the variable resistor? I'm assuming that the other two are either side of the resistor. Is the bottom lug a hard wired connection off the variable resistor (Connected to the 51,000 ohm resistor?) 

Here's the schematic:

I think I swap caps on the volume pot and want to make sure.

Also, with the On/Off/Tone Switch, there are also 4 connections: 2 on the back and 2 on the top. I'm assuming one is for on/off and the other pair is for tone. Which one is which? I haven't really looked at it, but I figured I'd ask.  

Thanks

Bernie
