How can I protect ML 436 monoblocks amplifiers?

"Can I espect a protection with the PS AUDIO POWER PLANT PREMIER POWER REGENERATOR ?"

Many manufacturers do not recommend using power regenerators on power amps. This is a question for a ML dealer or contact ML directly.
Also, using a power conditioner/regenerator on a power amp might possibly change the sonic characteristics of the amp.

My advice is to research high quality passive surge protection for the amps. Also, it sounds like you need the power company to check the line voltage coming into your home.

I contacted both MLevinson support, and they inform me to contact the ML distributor to Portugal, the company Genesis Technologies Iberica, but I didn't receive any reply from this company.

From the PS Audio I receive reply from Paul McGowan, and this was our conversation:

At my question, sent, the question of this topic, this the reply:

The P10 Power Plant would be perfect to make certain the voltage reaching the amplifiers is always 230 and to protect and improve their performance.

My reply:

The solution was 1 P10 for Both amplifiers or 1 for each amplifier?

And the other components? Cd PlayStation, record Player, pre- amplifier?

Each amplifier consumation was 560w

Again Paul reply:

You could use just one P10 but you'd be better off with 2. You can use the P10 to power the other units as well.

In the mean time my local dealer inform me that have a second hand unit of the Power Plant Premier to sell.
So I ask again to Paul if this unit cand handle to the ML 436 monobocks and receive this:

"Jose, this is a regenerator and works great for products. It should be able to handle up to about 1000 watts, so depending on how big your power amp is it should be fine. Highly recommended."

I had similar problems here with unstable voltage. I solved the problem with a Thor PS 10 power regulator conditioner. Below is the URL to the unit. http://thortechnologies.com.au/products/product/ps10-smart-power-station

A PS Audio P-10 power regenerator would be a very good solution to your problem.
