About 35 minutes on the outlets - thanks will check it out.

@laynes

If I were you I would get the outlets burned in first before spinning your wheels looking for possible AC mains power problems.

If you only use your audio equipment AC loads to burn in the outlets it could take a year, or more to burn them in... You need to connect a load(s) to the two outlets 24/7 for at least a week or two. You need a load that draws some current. At least 3 or 4 amps if possible. The greater the connected current load the better.

@laynes,

See article below:

@clearthinker those pre and phono amps used batteries build into the units or connected to a DC power inlet. That is different from using a cheap AC inverter running from batteries. I could word that differently. A cheap, high powered switch mode power supply.

The conversation has degraded to burning in AC power outlets. I think we have lost the plot on the conversation already. The op has not even verified there is a problem yet, but everyone is rushing to solve it without even knowing if there is a problem, or what it is.

This is what the inside of one of those low cost inverters looks like:  http://www.kerrywong.com/2017/10/01/teardown-and-testing-of-an-800w-puresine-inverter/  It is a high frequency switch mode power supply that generates the high voltage (~170V) and then a PWM stage, and then a filter. I don't see a lot of capacitors or filtering on the DC side, so there could be RF coming out. I don't see any FCC on most of these. YMMV

Old school ones with the big huge transformers are probably not as noisy.

I have battery storage device I tried on various components, prefer sound from dedicated lines and transformer based power conditioner. The cheap inverters in these devices is the problem, create their own noise/distortions. I assume those built specifically for audio, like the Stromtank have paid much attention to inverter produced noise.

It is this kind of audiophile sh-t that drives me nuts. All you have to do is buy equipment that has audiophile nut proof power supplies and you do not have to worry about anything except maybe lightening storms.
