Hi Leo, thanks for the reply.
I did read that one, and another from Cloudy Nights. The one I'm looking at is similar to one linked in the article (
https://ridgemonkey.co.uk/product/vault-c-smart-42150) so maybe it will be ok.
I like the smaller form factor as that'll be useful in also powering some of my synth equipment when I'm on the road.
Cheers, Dan
