I got a Schiit 'Mani' Phonostage but the Power supply i do not trust for long term reliability! Anyone know of a beefy jobbie? Its 16V A.C, preferably one with a Power switch save me farting about with the switch at the back of the unit!! cos id rather hide it away & not look at the ugly piece of Schiit  |

AC power supplies are more difficult to find and are mostly just a step-down transformer. There's little to fail if it's properly specified for the job. You could insert an in-line switch into the power supply cable if you want to turn it off?

Subject to confirmation, couldn't you make up a chunky 12V-AC* transformer supply? I made a small one for my MF X10-D to the Rock Grotto spec (I think the page has gone now) using a fully potted toroid from RS similar to this one which is totally silent, but rather more expensive than the similar VA-sized ones I sometimes use for work -
uk.rs-online.com/web/p/toroidal-transformers/2238544/
I think the secondary's were paralleled up rather than giving a plus and minus voltage. In my case, a switched IEC socket on the back and outputting via an internal chocolate block and fuse to a 2.5mm DC plug as M-F used - case was a common abs project box. I made this many years ago and long before I did this kind of thing for a living...
* memories of measuring the output voltage are old now, but I think the 12V transformer wired the way it is, gives around 14 - 15VAC on the output. Mine is a 30VA transformer, but knowing what I know now, you could easily overkill to 120VA size in a bigger Hammond style project box? I'm assuming regulators are in the Mani itself...
P.S. Forgive me if the suggestion above is total crap for the Mani. I didn't think a larger transformer was needed for IC based op-amps either...
Rock Grotto do an AC supply specified at 12V @ 30VA for the MF X series of boxes. I think one of them can be specified for 15V (I think it's one of the AC ones), so bearing in mind the price is better than the posher looking £200 jobbie I've seen, if it floats yer boat, why not email and ask - he's a friendly chap and seems to have 'ears' if his X10-D update kits and choice of upgrade valves is anything to go by  |

Paul Hynes once told me that Multicomp are the best of the reasonably priced toroid brands. You should be able to get what you need from Farnell, plus a case to put it in.
