My set is a code 125. I got a package of data from Chuck Schwark. Even with the large schematic it's hard to see everything because of the complexity of this set.

The bakelite blocks in the power supply (two of them) are for a .15uF cap across one of the filter chokes and the second one is for AC line caps to ground (0.015uF). I believe the bakelite block with the 10KC coil is in the chassis which I haven't touched yet. Here is a photo of the chassis underside showing (I think) that bakelite block.
   

I also think someone installed a cable and box on the chassis for a phonograph plugin attachment. There is a switch to go between phono and radio .

Thanks to all for the feedback. As Arran said, it is probably an older replacement and yes it has a grid cap so I will ...georgetownjohn — 09:32 PM
