Post Subject: Noise on the ground connectionPosted by drdna on: 11/26/2020
The way it is described, I have to agree about taking the Pure Power to a trusted local repair shop to get it scoped out.
I will just say again that repairing the Pure Power seems to fix the problems, for those who have been able to get their unit back.
If you have a oscilloscope, it would be of interest to see the waveform going across the connection between the Pure Power Ground and the Phono ground. You can also try adding a capacitive filter in the connection to see if this blocks the noise.
This can reveal more about what may be causing the noise, but as I said before it is probably best to get it to a local repair shop before catastrophic failure occurs!
