Your set works and looks gorgeous! I would just use the 'ol 8 volts method if you are unsure of a restore. It sounds like that is all you need. I would let it sit at 8 for about 2 hours and then test after it has cooled down. I too have the CR-70, I don't often use the restore, but did try to damage a dead CRT one day just to see what I shouldn't do, well, it just wouldn't hurt it. It shut down before any damage was done. This almost dead CRT is still functional. The CR-70 is probably one of the safest on your tube. But, like you said, why take a chance on such an old and rare CRT. The most I have used the auto-restore is on a weak tube that didn't come back on 8 volts. I interrupted the restore after the first 7 or so second burst that it gives. I didn't let it go all three times as per the instructions. It also says that interrupting the restore is ok if you want. Tube came back nicely. I try to be as gentle as possible.
