Tablo Quad Legacy Squeaking? Check Your Power Supply Voltage

I experienced a high-pitched squeaking sound coming from my Tablo Quad Legacy. After trying several troubleshooting steps, I measured the power supply’s output voltage with a multimeter. The reading was only 8.6V, significantly lower than the expected 12V. I replaced the power supply with a new 12V unit, which completely fixed the noise. I hope this information is useful to others facing the same issue.

Interesting - did it squeak all the time, or only periodically? Mine emits a med/high-pitched (not quiet) squeak periodically, which I’ve sort of correlated roughly to the times when a recording might be starting. I kind of guessed it was the drive spinning up or something, but never really investigated as it is short lived and not too irritating :slight_smile:

Thx!

First intermittent then regular. Just search “how to test power supply with multimeter”. There are multiple videos. It’s a simple and fast test.
