Need Help Identifying E.H. Scott Amp/PS Chassis

[Ben Hase]

I picked up a large E.H. Scott chassis among some other pieces of tube equipment this past weekend. The original owner said that he thought it came from a Philharmonic but some things are not lining up. The power transformer is Black and it has rectangular multi-pin interconnect sockets. Tube compliment is (2) 5U4, (4) 6L6, output TX is marked. I also have an external crossover chassis. Images to follow shortly.

The Power Supply/Amp chassis transformers tested well. I did not test with any tubes in circuit. My standard practice is to rebuild a power supply that old and didn't want to risk damage to the transformers. The original owner said it had not been powered on since he was a kid. 

Anyways. Both devices are now up on the auction site. Taking offers. 

Thank you everyone for your help identifying these items.
