The 5u4g probably surged the cap on turn on. That's why a 5ar4 is safer to use. It has a slow heat up, less surge.

I don't think so, otherwise then we have major design problem here. True that a 5U4G draws more current than a 5ar4 at power on, but not only that's the tube that I have been using with the mk2 version of that pre-amp for 4 years, but the 5U4G is included in the list of supported tubes by this design. Better yet, the 6Z5p, the default that comes with this unit is even more taxing on the power supply than any of the mentioned rectifiers.
The reason I prefer the 5U4G is because I find it to be smoother sounding than the 5Ar4.

Well, the dealer Garry, is up there in Canada with you, so he should hand deliver a new one to you.

You do know Canada is the second largest country in the world, in fact I am closer to Florida than British Columbia where Garry is located. If I knew he would ship from China I would have not placed the order.
