Parting out NEC XG1100

How many boards does that share with an 852?

when you say tubes shot, how worn? Large area or small? 

I imagine this is an AC set?

They are pretty dark. Yes AC. This was also just a test unit. I am not sure about the deflection board either. It has been so long I dont remember if this was the one that ended up with a deflection problem. I am clearing out stuff even if stuff goes in the trash.

There are two boards on the lid, H-DEF with the tunnel heatsink, and the other is the HV unit. Both are interchangeable betwren the models, although th HV unit has some sealed trimpots those should be set to the flyback transformers.
If I were you I'd keep an A-drive board as it has two STK392-220, those are hard to find, and othetwise run very hot on F-drive and C-drive boards. The F-drive is running cool and fail rarely therefore it is a good source for the STK chips.
