model 640? - NostalgiaRadioTime - 06-01-2016

Just took the chassis out of what I think is a model 640 (tombstone) and noticed a discrepancy right off the bat from the tube layout label in the cabinet:

   

Seems the #80 rectifier tube is swapped location on my chassis with one of the electrolytic cans:

   

Note how the tube is flush with the edge of the chassis, whereas on the tube layout, it's at the location of the can.

The tuning capacitor has "650" stamped on it

   

Since the labels are missing on the chassis, I'm trying to determine exactly what I have. Is this a bona fide model 640 and if so what code would it be?

Thanks!

Yours is 640.

The diagram...not sure what it is.  Could be a version. The tubes lineup is the same.
