Hum from the ZROCK, what to do?
12/31/18 at 22:08:21
 
Hi,
my ZROCK2 25th has a slight hum coming from the device itself. When I press a little on the top of the device it goes back to a very minimal level.
Anyone else experienced that?

Something is probably shook loose in there.

In case you guys experience the same, here my fix: everything was nice and tight in there, but the transformer seemed to have touched the bottom plate and caused the hum, so I put a bit of heat resistent rubber between the transformer and the bottom plate, now it is whisper quite Smiley

Saved yourself from having to ship it back to the factory.

Indeed!

Steve, if you are reading this thread, maybe something to consider doing as a default in new builds.
