Thanks for the information. I had looked at those pictures and others elsewhere, but found that some of them had labeled the 660 as a 665 and vice versa, so I was confused.
Using these pictures, I can see that I have a 660X. Honestly, I like the 660X cabinet better.
I printed the schematics for each and noted the differences between them. I don't know if the 665 chassis was actually superior or just less expensive to build, as I have noted the deletion of several parts on the 665 chassis. At least my experiences with the other Philcos I have will help --I have a 91, a 16B, two 37-116s, a 38-116 and a 38-690.
