The 620 and 630 are very similar electronically. As Todd (Tab) said, the 620 does not have a shadow meter. Both are great performers, and have real SW bands, none of which is wasted as with the 610, 640 and 650 which all have a band that is dead except at the very top of the band - the "police" band. The dial scale on that band only shows blank lines until the very top, also - the circuit apparently does not oscillate until it gets into the range of frequencies covered (2.3 to 2.5 mc or so).

Now, keep in mind that Philco crammed a lot of parts and six tubes into a chassis the size of a 60, so they aren't the easiest radios to service - but the effort is well worth the trouble.

The 620B is smaller than the 630B, and does not have the ebony inlay veneer on the front panel like the 630B has.
