thank you david!
I am working off a print that i got emailed to me in like 2003 from a member at notstalgia air. I printed it out back than and put it inside the radio where it lived for all these years. I notice nostalgia air still has the code 121 still up ,, although i suspect i am code 125. Chuck at the philco work bench is getting me a package together.

some pics for the board.
 
finished inventory of all components
for the record, 46-1226 code 121 schematic is what i feel comfortable in saying 99% accurate for use in working on a code 125.

The largest difference is the filter capacitor section, the code 121 diagrams do not match what i have infront of me, that i can work around.
the wiring on the on/off switch does not match either.... one leg of my on/off sw lands on the rectifier V8 tube,, the schematic says otherwise.

Let me be clear though, i have  no evidence to prove that the reciever i am working on is infact a code 125.  I use code 125 because that is what the cabinet lable says.  Nothing on the reciever tells me i am a 46-1226 code 125.

i am providing pics to aid in a historical reference point of what components were original.  this one seems to be all origininal except for a couple of small issues.

i have removed the audio output transformer for access reasons.

there are two dozen compacitors that will be replaced.  Next i will lift, isolate and measure all resistors and pluck some replacements from my stock. 

One thing about the resistors i worry about is the wattage on "some" as they are very large or are being heat sync'd to the chassis. 

next up would be an OCP at the power chord entry point which i may mount on the top next to the large transformer for ease of access using a fast blow 3amp.  Just guessing right now on the ampacity requirements.

next is a polarized chord and to finally locate a small remote mounted isolation transformer i can phycially attach / hide inside the cabinet so it has its own onboard iso-xfrmr.

I can simply make my own by disecting wall wort power supplies , goodwill has lots of random power supplies and often i see two matching ones.
I did find two matching 120vac to 18.5vdc wall worts. i can simply put those two xfrmers back to back to make isolation,, they are both 450watt.
i can just delete the rectifier section , put both xfrmrs inside a project box and see how that plays out.
the diagrams dont tell me the unit power draw
