Hi Paul,

Hopefully, I can get your help / suggestion on how to solve my PPP problem. I do have quite a few PS Audio products but this particular PPP ( I have 2) has been giving me trouble.

The PPP is connected to the main (220V Hong Kong) and out of a sudden, some relay inside starts to click like crazy and switching the PPP on or off does not make any difference. I have been to Radar twice and they are kind in helping me to solve the problem. But they seem to have problem reproducing the problem. I have therefore taken a video and hopefully you can help to shed some light on how this problem can be solved? In this instance, the PPP is not connected to any load at all.

This clicking noise you hear is the protection relay in the PPP going between the incoming line and the output of the regenerator. You can see the voltage changing on the front panel from output of the regenerator to input of the regenerator.

We have seen this problem before on some AC lines that are problematic and it can just start and can also stop on its own - which is probably why it doesn't do it when you take it to Radar.

See if they can loan you another unit to try and with any luck that will be less sensitive to the line problem. We have not figured out what exactly causes this to happen with different AC lines so we don't have a specific cure. We do know that different PPP's act differently on these problem lines.
