By the way, the underside of your chassis is not untouched, I can see at least a few replacement paper caps mounted underneath, some may be to bypass failed block capacitors. It's been a while since I looked under the chassis of my 620B, most of it's issues are cabinet related, but the radio always worked so I never got around to working on the electrical part.
