>> A point, possibly off-topic. In the UK the "online shop" is now essentially a silicondust page that buys your product through Amazon. The first HDHR dual tuner I bought came from the same page but Amazon was not involved at that time.
> Long ago, I would have bought a replacement power adapter at Radio Shack. Nowadays, I don’t know of a physical store that would have such an item in stock. Let alone a quality product. The pandemic situation is such that I don’t want to go pawing through a bunch of bins. (I’m going through chemo.)
> BTW, I think SiliconDust’s reputation for problems is overblown. I purchased my first HDHomerun before they had failures with the wall warts. They clearly got a bad batch of power adapters and did a recall to make it right. Ever since, they’ve provided replacement adapters at a nominal cost. As Gary says, these things have never been expected to last forever. (And I think they are often killed by surges in lightning-prone areas of the world—which is not me.) I honestly can’t remember if I got the free replacements from SiliconDust during the recall. Either way, my HDHomeruns have outlived multiple configurations of backend hardware!
> Incidentally, the power supply I’m using is a ‘universal’ type: selectable 3-12 V, interchangeable tips, and with a switch to change from centre-positive to centre-negative. However, the HDHomerun wants 5V and the nearest setting I have is 6V. Also, the tip is supposed to be 5.5mm OD but mine is 5 mm. It works but it isn’t really right. My box of used power adapters does not have anything supplying 5V. The closest I have is 9V; most are 12V.
Of course you will almost always have a powerful 5v supply nearby, if you care to make up some
 Assuming that your backend isn't a Rpi or a NUC or something like that, of course.
 Also assuming that your HDHR(s) are near enough to your backend.
