For all you BeePre 1 owners,  do you have any experience with or are you aware of a reasonably priced volltage regulator that you can plug into the wall and get a constant 120 VAC out to plug the BeePre 1 into?  My house voltage here in West Texas during these hot summer months varies during the day from 114 to 119 VAC which is playing havoc with my BeePre.  I currently have the BeePre plugged into a variac but I don't like having to manualy adjust it throughout the day.
Any thoughts would be appreciated!
Dave

I have made a few boost boxes over the years for this situation.  You can use a power transformer with a 6V-CT secondary (1A rating is fine) and a 3 position rotary switch to have +0, +3, and +6V boost on your powerline.  It's not a bad idea to slip a fuse in there too.  In practical terms, you can power up the BeePre and just turn up the boost box till the regulator dropout noise goes away, then all is well.

Thanks Paul!  Would you happen to have a schematic you could share?
I really appreciate the help!
