Hi, Lee ! Judging by the schematic, as I said before, when properly aligned, the radio should have very good selectivity and sensitivity because of the TRF stage in all three bands. Should be a real pleasure to use with a longwire antenna and decent ground, good for DX in general, on the BC band as well as SW, AM only of course, no SSB or CW. (To be honest I only have ready access to the schematic for the 37-620 handy, but the 630 is much the same except for the shadowmeter circuitry.) Order the right schematic from Chuck Schwark, you will be glad you did. A good clear schematic is the first place to start. But I am verging on "electronic restoration," so I'll leave any more for when you start a thread on this there.
