Reviews and questions about the entry-level MPC500

Hmm so I spoke too soon on replacing my capacitors as per the pinned thread https://www.mpc-forums.com/viewtopic.php?f=26&t=185081&start=15

The noise has reduced but I'm still getting a lot when I activate Record mode on battery/PSU, Backlight/No backlight, Monitor On/Off, Different/No input device.

Here's an example:

Very audible at 0db and seems superimposed on any sample I record. Is this typical sampling noise?

Would someone mind uploading an example of their "normal" MPC 500 noise floor with no input for comparison?

Here are test tones I created:

And the tones sampled on my MPC from my phone headphone output:

And from my laptop headphone output:

Having replaced the decoupling capacitors I'm not sure what else to try??
