Yes, that describes it. This is THE characteristic noise when there is a defect in the Pure Power unit. As far as I know, nobody knows exactly what electromechanical manufacturing flaw causes this. As you remember, i also had this issue. Then, my Pure Power failed completely. Then after a lot of effort and time, I got my replacement, which has been completely silent. It's a bit of a roll of the dice until Damien and Richard figure out what is causing this.

This would be fun. I often have fantasized about this, but it would be a lot of work modifying all the circuits around the rectifiers, etc. After all that, it will certainly affect the sound, but will it be a positive or negative change?Rerurn to Romy the Cat's Site
