I haven't measured it but just going my the filament brilliance it's more than I ever do manually.

Yes, I have used the auto and manual restore/rejuv functions on a Predicta and it didn't blow out the filament. I suspect it's going a certain % higher than the filament voltage setting.

Not sure if a LM317 would work since although it's DC it's not filtered.
