Anyone have a real DOD ef440?

Hi,

I was wondering if anyone who owned one of these could pop it open for some kind of definitive trace.

I have this guts shot from an ebay sale (?):

and it has 2 resistors more than the online schematics (16vs14). It also has a couple values (4K7, 6K8, 100ohm) that do not show up on schematics.

My guess is that they changed the values for the resistor after the input cap and the one going to the range pot to 10Ks at some point. The 100ohm is probably power supply related. That still leaves a rogue resistor doing something somewhere.

I know the GGG schematic works fine, it would just be nice to have a clone be an actual clone.
