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.

Brian, that is why I bought one and it works just fine. In general, I am quite happy with the Meanwell lookalikes I have bought over the years from AliGood and BangExpress.

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!
Just found this thread by chance.

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. 🙂

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.
