I've just about finished restoring my 610 and it has been interesting. I found two different schematics for this radio, the original version and the last version. My radio turned out to be a mix of the two. It mostly followed the last version, but had some caps that did not show up on that schematic and were in the original version. I guess Philco cut in their production changes in a piece meal fashion, thus the mix I found in my radio. Makes thing interesting.
