Taken delivery of a new Powerplant 3 (P3). I connected my 15W valve integrated amplifier, valve phono stage and Rega TT power supply. Played music for less than an hour when something went wrong with the P3 and it caused the a shuddering distortion noise to come through the amplifier. The output LED on the P3 was RED - I did not see if it was flashing or glowing solid - I was literally freaking out. In my ‘flight or fight’ (ie. freaking out) mode I turned off the amplifier and phono stage to stop the noise, then turned off the P3.
Subsequently my Rega TT power supply no longer powers up. Haven’t been able to check if phono stage has been affected.
I’m currently using the P3 to listen via digital sources without any obvious issues however with only the amplifier connected to P3. Can anyone shed light on what may have happened to cause the P3 to have a tantrum?
FYI. 15W valve integrated amplifier power consumption is 87W, valve phono stage power consumption is 17W and Rega TT power supply power consumption is 17W - so load shouldn’t be an issue.
