Does anyone know the difference between the 620 and 625? The schematics seem to be the same.
Comparing the two schematics, it's obvious that there are first audio amp bias component differences, many differences in the RF/IF stages component-wise, many AVC line component differences - (delayed AVC in the 625), 620 has AVC line to IF tube, 625 does not, etc.
Thanks, Chuck. I didn't look closely enough at the schematic.
