Hey everyone!

I have been working on a Philco 51 chassis. When I received the chassis it had a Bakelite block with what appeared to be a line to ground cap on the primary of the power transformer. The block was missing the side with the numbers on it so I had no idea what the part number was.

I replaced all other caps and bypassed the Bakelite block with the line to ground cap and everything worked great! I figured the line to ground caps were in there for a reason so I rebuilt the Bakelite block with a .0047uF safety cap and wired in the Bakelite block to one side of the primary of the power transformer.

The problem is when I bypassed the line to ground cap there was no voltage on the chassis and now with the line to ground cap I do have voltage on the chassis.

Here is link to the 51 schematic: http://philcoradio.com/tech/images/51.jpg

As you can see there is no line to ground cap on the primary of the transformer. So I am no sure if it is needed at all.

Thanks,
