Philco 53-564 IF transformers
#3

Philco finally came to their senses and put that 2nd IF transformer inside a can by 1953,....but it is essentially similar to the  2nd IF transformer I botched in the 39-6 C I . Had they done that in 1938 , I wouldn't have made my mistake of pulling one of the wires off the transformer. ( I ended up re-winding the secondary winding by hand....horribly-sloppy but it works!)

It does look like you could add in the 2 extra caps with a terminal strip.  The entire assembly was exposed previously, so your mod may still work ok without horrible side effects, but pay attention to where the 47,000 ohm resistor is , in relation to the caps.
