oops, I thought I answered this this morning...still half asleep, I guess... 
A 37-623B cabinet is the same as a 37-620B cabinet.
As for physical size of chassis, when considering AC-only chassis, the following will fit:
37-610, 37-620, 37-630, 37-640, 38-610, 38-620, 38-630
The 37-640 is indeed the same physical size as the 37-630, 37-620, etc. It does use seven tubes, but everything is crammed into a smallish chassis. I have a 37-640 chassis in my 38-624T Big Bullet cabinet, it fits just fine.
