yup, i studied the brochure, and i found nothing in there to indicate otherwise.
so called "power regenerator" is just another variation of line conditioner, that is how i see it.
Hmmm....pardon me, but I think your last statement is somewhat vague.
Variation is the "word" here.
The "power generator" is different in a sense that it converts incoming AC to DC, rectify and smooths it for ripple, regulate it, feeds it to an oscillator to re-create the AC, then amplify the AC from the output to generate the clean and re-generated AC at a set amplitude. In the outcome, you can control the voltage, power factor, and wave type where it can be a pure sine wave or a combination of it plus its harmonics applied at an specific phase angle set at the oscillator board before amplification.
How can that be the same variation as a line conditioner made up of chokes, LC networks and MOV's? In essence, they both do conditioning but that is where the similarity ends or variation as you put it.
Maybe you are referring to the "Ultimate Outlet" where it is made up of a big torroid choke but not the "power regenerator". There is a very big difference in the application between the latter and the former.

How? What improvement?
Soundwise on my audio rig. That's how i hear it.

Reflected waves from distant transmission lines produce harmonics, inductive loads produce transients, lightning strikes, even the cars's ignition system can couple signals to the power line. The pc's psu can produce EMI/RFI, so with microwave ovens.
now with line conditioning, all these are minimised by employing filters such as provided by chokes and capacitors, while have very low impedance at 60HZ, they present a very high impedance at RF.
MOV's are also very important part of line conditioning, since they absorb energy in the event that the voltage exceeds the nominal which is 220volts. that is why they are installed after the fuse.
Voltage regulators, like Yaden, STAC, or STAVOL also form part of line conditioning. In my case i opted for an isolation transformer to break gound loops and avoid nasty shocks.
Here in our area at Laguna Technopark, voltage reach up to 240V especially weekends and Monday morning plus we are (very) close to transmission lines of Napocor will a line conditioning and voltage regulator do it for us or we also need isolation transformer? What would be a good combo in your opinion? All of the above?

alexq, did you have your tv connected to an avr at the time or was it plugged into the wall?

It was plugged on my Stavol.
The Samsung technician told me that if I had my LCD TV on, it could have survived the spike. He told me that since the PSU board of the TV does not have any load except for the standby power, the PSU board has to absorb all that energy from the spike.
The warranty just expired (a couple of months), fortunately, Samsung gave me 25% off the repair.

and after the warranty expires, i will most certeinly put those MOV's inside the units, because you will never know when you will be without a power strip. besides inside the unit is the best place to put those MOV's in.

Sir Tony,
Is it ok to install MOV and filtering caps in your ac outlet? So before you plug in your AVR's and Line conditioners medyo safe and protected na sila? Or still best as you have mention above, inside the apparatus?
