Thank you all. Just to be clear, I was not asking for AC-DC dual voltage PSUs. I'm 99% sure I'll be using Tom's SMPS86. My intention is to plug a laptop charger to the enclosure, say 24 or 48VDC, and an internal isolated DC to dual DC converter + regulation. Why? Because I seek two features,
- Avoid working with mains
- Small enclosure (ie avoid toroid + PSU)
Closest thing I've found is Traco Power TEN 60-2425N but it's half the power of SMPS86.If you do find something that you think is a good fit, please post a link. I'd be very interested.

Ah! I've been down that road too for similar reasons. I haven't found a good solution yet. I'm sure you can build something, but there aren't a whole lot of good solutions available in the ±24-±36 V space you'll want for a MOD86/286. Usually the negative regulator is the issue.
Vacu, I'd be cautious about buying a 'random' SMPS off eBay.
Yeah. There are several tear-down videos of cheap supplies, that show failures from short circuits between primary and secondary - i.e. have the potential (literally!) to kill the user. I see no reason why the eBay supplies would be any different.
Tom
Brian, that is why I bought one and it works just fine.
But are they high-pot tested like the real products are?
I get it. Your money, your time, your life, but still... Some of these products are cheap for a reason.

RPS 200 Power Supplies
I built one dual Mod-86 powered by Mean well RPS-200-24 power supplies, and a quad Mod-86 powered by mean well RPS-400-27 power supplies. The RPS-200 run much cooler than the RPS-400. Both systems are able to run at high volume with out any power supply issues. Best regards.

Very cool!! Thank you for sharing. I really like Mean Well. Their products are well spec'd and meet their specs. I've also had the opportunity to deal directly with their customer support / applications team. They respond within 12-24 hours even to a small company like me, and respond to questions that many others would ignore, such as "which temperature sensor do you use?".
It's good to hear that the RPS-200 is useful for the MOD86.
BTW: If you get the chance, I'd suggest adding some heat shrink on the connections for the mains switch.

Ha!
10 hours of listening today and I could've done more.
An externally hosted image should be here but it was not working when we last tested it.

Indeed.Sleep is overrated, luckily as Neurochrome amps prevent such.
I have literally listened to anything I could think of. Wife and kids were busy today so I had free time and when I totalled it up, it had been playing for about 10 hours.
I am a huge fan of these amps.
Slap one of Ian's DAC'S in front and you will probably never sleep again. (he is also a Canadian ! )

Maybe that's why my sleep quality takes a hit every time I release a new product. Silly me. I thought it was stress.

Ha!
Just found this thread by chance.
Proud owner of a 686 and its awesome.

Hi Oliver, looking forward to hearing it on the end of the Neurochrome differential pre amp

Ha, fancy seeing you here.
Yes, we will make that happen. 100%
I'd love to but don't understand it all lol.Slap one of Ian's DAC'S in front and you will probably never sleep again. (he is also a Canadian ! )

I've just ordered an Orchard Audio Pecan Pi to replace my Allo Boss.
Hadn't realised how coloured the Boss is untill I stuck the 686 in the system.
Seems a decent upgrade on the Allo Boss.

Though there is a certain synergy in mating a Canadian designed DAC with Canadian amps.

I did look into ians creations but at this point, its far too advanced for me to get my head around, so I'm told lol.
I haven't given up on the idea, just decided that as an immediate solution I could do far worse than the Pecan.
