I have a Philco table radio , model 49 ,and i have it recapped,,,,,except for the caps going across the power supply.
 The part  number  for the block is    3903 ODG.
 I have looked for a drawing of this block and I  can''t find one 

   Please give me a DRAWING  of where the .01 caps connect to  for this block
 Thanks

Here's some information from our Library:
https://philcoradio.com/library/index.ph...lock-data/

The 3903 ODG contains two 0.01uF capacitors wired as you see in the diagram. The "O" means the wax used in the block is high melting point, the "D" means the two caps are the same value and the "G" means that the mounting screw and hole are grounded.

Hope that helps.
Cheers,
Bob
