How To Best Deal With Voltage Surges?

OK, let's lay out the background:
- In July of last year, I was transferred by my company to Caracas Venezuela. Naturally, I brough my stereo which at the time comprised two Aronov 9100 monoblocks with auto bias circuits.
- Although my system sounded fine in my new digs, the audiophilia nervosa bug compelled me to upgrade my amps to a pair of CJ Premier 8 XS monoblocks - which do NOT have autobiasing. These were a MAJOR improvement over the Aronoxvs...for a about 2 days. On day three, I fried 5 EL34's and one plate fuse upon turn on. One week later, new tubes and fuses ($ 8 each at McMaster Carr!!) arrive, and amps are GREAT...for about one day.On the second day, fry another 5 tubes and plate fuse on same amp, plus two more tubes on other amps.

So..begin to check everything out and find out that the voltage can surge to as high as 140 volts. The CJ's do not like that very much,since a Voltagr surge leads to a big bias current surge on the output tubes. I'm sure the rest of my gear aint happy either, but is unable to complaint as eloquently as the CJ's.

So...I'm in the market for the best voltage regulation I can find. Power conditioning per se is handled quite well in my system by a Marigo Reference unit and Bybee filters for premap and source components, and by Ultimate Outlets for the subs and amps. What I need is a unit that will keep the voltage pretty much at 120 volts. Given the size of the amps, Power PLants arent really an option (too much money, too big). Seems like the Monster AVS2000 or the Exact Power EP15A will do what I want. Would appreciate comments on these or alternative solutions. Thanks!

I just purchased a Furman AR-1215 voltage regulator/surge
suppressor. So far it seems to work fine with my front
end equipment (Levinson 37/360/380S and TacT RCS 2.0).
At least I sleep a little better at night.....
