Cheers vmax much appreciated …iv actually got my p20 running at 234 …should b 230 …but yep reading about these fuses i have to give it a go 
Cheers Michael …ill check that aswell
Another way to check fuse value is to remove the one that is in your P20
and read the value on it…Fool proof because it will be the one provided
and installed by PS Audio…

Awsum thanx for that davida…much appreciated
Be careful with that method of determining the fuse value. Someone in the US received a mk 2 with a 500ma fuse instead of the correct 1 amp. It is easy enough for the wrong value fuse to accidentally end up in the wrong bin.

Hey sixpack1
Thanks never heard of that happening before…do you recall if it was
over or underrated…Just wondering if it was purchased through PS
Audio or on some reseller aftermarket…’
Thanks for the heads up.
Best wishes

It was a direct shpment from PS Audio for the Beta test. It was half the value it was supposed to be. That is better than too large. It proves tha 1 amp is plenty for the mk 2 so no one should be buying a 1.25 amp fuse unless they want to endanger the power transformer.

It’s taken weeks, but my Purple seems finally to have gained some consistency for a few days. Very different to my experience with various QSA and Telos fuses, that had settled in after a few hours and didn’t budge thereafter. It has made it difficult to find my bearings with the Purple, but it’s certainly the case putting the stock fuse back into the amp reduces performance, so it’s clearly a win. The other tricky thing with gauging effectiveness is price; the Purple seems a good value against the QSA yellow with similar quality gains (in different areas) at a similar price.
Out of curiosity I looked for fuse values in the MKII manual. They are not listed.
It is marked on the back of the DAC.
