One of many hack job repro boards out there, with no documentation.

Thanks for the reply.

The design and font used is similar to dezbaz boards.

Would an LV2000 work on this board? This is one of the questions I have, and possibly get it working again.
I would assume it pretty much follows the latest OG P314 BOM. However, it seems to already incorporate the linear regulator solution as is.

It appears that the regulators are built in, but the feedback networks have been removed
LM317, LM337 next to the connector.
So, clean the holes and add back the missing discretes. The circuit is simple. When testing on the bench, just add + and - input voltages to the unattached board and confirm the regulators are functional. Then worry that the deflection circuitry is working.
If this is a "desbaz" board, then the schematic is likely posted on his website. Go fish.

BTW, whomever soldered that board originally should have their soldering privileges permanently removed. What a mess. 
It was likely a prototype somebody was making that they had issues with.
I say this because they used ground fills on both sides of the board. I have made several 6100 clones and found out the hard way during prototyping that you can't uses ground fill because of capacitance.
What you get is coupling between the drive transistors and the sense resistors. This creates "noisy" vectors that can not be corrected.

You can test it out with some 24V switching supplies and ignore the LV section all together. That will at least let you know if it is worth trying to save.
I can loan you a test setup with heatsink mounted power transistors if you don't want to risk good bottle caps.

The parts were damaged/broken during removal.

I am still in the research mode for board information.
