I have no idea how that amp will tolerate it though, it's quite different from most proper amps since the output valve is a ECC82 preamp valve and the transformer is likely to be tiny - I haven't seen inside one of the new ones.
You can use it through just one of the speakers if you set the cab to stereo, that will be fine - I don't think you need another plug in the second jack to turn off the speaker, but you'll be able to tell just by trying it.

I think I'll keep looking for a different amp.
BTW The cab has two inputs (one labelled mono) and a switch to go from mono to stereo.

Without casting any aspersions!! The HT-1 was the first 1W amp AFAIK to use an ECC82 in push pull as an OP valve. Now the HT-1 can have any speaker impedance fro 4 to 16 Ohms and since there not many ways you can wire that circuit I bet the Marshall is very similar, (not saying they copied it of COURSE!) .

What I don't know is whether by marking it for 16 ohms only Marshall know it's a bit fragile, or do they simply intend it to be run with one of the own cabs which are typically 16 ohm.

"I did think that too, but when you've seen the failure rate of the transformers in some Marshall amps, I'd be inclined to err on the safer side than I normally would..."
IC, ^ do they fail from arcing or overdissipation? If the former connecting a lower load than 16R will actually help there. Won't of course be kind to the ECC82 but they are tough lil buggers and in the One at least are cathode biased so anode current is inherently limited anyway.
For the (my) record. I had just one HT-5 OPT fail, punched through pri to sec and blew HT fuse, that's one of thousands by now. Never had an HT-1 OPT fail but I retired pretty soon after its launch but it has been a successful amp so we'd know? !!
While we are on the One? DO NOT ye gitist fiddlers fit anything BUT an 83 and 82 in the right places! Nothing else will handle the output and the load Rs in the pre amp section are pretty wee and might burn out. Not heard of it happening, jus sayin...Guess that also applies to the Marshall but then, not that fussed if you ***k them!

A bit annoying really - I could just use one side of my cab. Or seek an alternative amp. But the Marshall (speaker output aside) is the one that had all the features I wanted.
Whichever it is, the rate is exponentially higher than any other brand - I know Marshall have sold a lot of amps, but I’ve easily replaced more transformers in them than all other brands put together. In many cases just one model more than most other brands! Even very common brands like Fender and Peavey.
It’s true that some of them are caused by poor design and component choices in the speaker circuit, but it also applies to PTs as much as OTs, so I think it must be a design spec or supplier quality problem.
