[Milsurplus] BC-1004 Modification Question

[Joe Connor]

Jim, the nomenclature tag says only BC-1004. I haven't gotten a good chance to get under the hood of this monster yet to compare the wiring and layout to the different variations shown in the technical manual. I peeked under the chassis and saw a prior recap (orange drops and BBODs). 
Yes, I got the military power supply. The connecting cable needs some work so I'm currently using another power supply on this receiver. 
Once it hits the bench, my plan is to: (1) replace the BBODs and out-of-spec resistors, (2) make sure the caps inside the cans have been replaced, and (3) determine if the caps in the RF deck have been replaced yet. 
I'll also spruce up the engraved lettering on the front panel. I am always amazed at what a big difference that makes. Cosmetically, this is one of the nicest SP-200s I've seen, so I plan to do it up right.

 JoeAs a guess, potted transformers and chokes with terminal strips instead of flying leads, hermetically sealed capacitors and oil filled capacitors instead of electrolytic.  These items are listed in TM11-4054.  
There is supposed to be a list of MWO's in FM 21-6, but I could not find it.  Did you get the power supply with the receiver?  BC-1004 -A or -B or -C or -D?Jim

I picked up a very nice BC-1004 this week. The nomenclature tag says that it was made by Hammarlund. Underneath that section, it says it was modified by American Television Labs Inc. What kind of modifications did American Television Labs make?
As always, thank you for your help.
