Gieseler Audio Posted February 3, 2017 Share Posted February 3, 2017 Low noise 9v, 12v & 15v 1.5A PSU I’m not sure if everyone is aware of this model so just a quick bit of info. It is very similar to my standard 5/7/9v unit but just with higher voltage outputs. Price is slightly higher at $325 delivered due to the much larger 16v 2.5A external transformer. I ‘ve rated it at 1.5A as that is the regulator rating but due to extra headroom with the large transformer it is good for about 1.8A (at 9v & 12v) before current limiting chops in. The 9v, 12v & 15v voltage output is user changeable via a PCB jumper setting. 2 Link to comment Share on other sites More sharing options...
Guest scumbag Posted February 4, 2017 Share Posted February 4, 2017 Clay So just to confirm, and hopefully not a thick question, if I were to use this with a device that draws 12v then the internal regulators will allow it to happily output up to 1.8a if required from the device that it is powering?

Juicester Posted February 6, 2017 Share Posted February 6, 2017 Do you do a 24v version for phono stages? Link to comment Share on other sites More sharing options...
Gieseler Audio Posted February 6, 2017 Author Share Posted February 6, 2017 Yes I can do a 24v version but it is fixed output with no different voltage options. 1.4 A max Cost $325 delivered. Link to comment Share on other sites More sharing options...
Gieseler Audio Posted February 8, 2017 Author Share Posted February 8, 2017 hey guys thanks for you support on this. I can hardly keep up with orders at the moment. There are now 50+ of my low noise PSU's in the field now. Just bench tested the 9/12/15v unit & at 9v it is good for 2A - not really designed to run at that current all day though. 3 Link to comment Share on other sites More sharing options...
Gieseler Audio Posted February 16, 2017 Author Share Posted February 16, 2017 The 9/12/15v unit works very well with the new SOtM SMS-200 - I pre set it to 12v out. 1 Link to comment Share on other sites More sharing options...
Suopermanni Posted February 16, 2017 Share Posted February 16, 2017 Just got my 12V Geiseler LPS for my LH Labs Infinity X. Initial impressions are good, a rather more punchy sound that I've heard an ESS Sabre DAC produce apart from Audio GDs. Going to let it run for a bit and see what happens. 1 Link to comment Share on other sites More sharing options...
Suopermanni Posted February 17, 2017 Share Posted February 17, 2017 Okay, the LPS has made a noticeable difference in performance. Even if using Youtube weirdly enough. Link to comment Share on other sites More sharing options...

a.dent Posted February 22, 2017 Share Posted February 22, 2017 Hi Clay, Can you do a 12V 7A PSU for my Mytek Brooklyn? Cheers Andrew Link to comment Share on other sites More sharing options...
Gieseler Audio Posted February 23, 2017 Author Share Posted February 23, 2017 Holey smokes 7 Amps! Unfortunately I don't have a design with that high of a current. Link to comment Share on other sites More sharing options...
a.dent Posted February 24, 2017 Share Posted February 24, 2017 OK maybe 7 amps is overkill. Probably 4 amps will do it. Any chance of doing that? This from the specs page. Link to comment Share on other sites More sharing options...
Guest scumbag Posted February 24, 2017 Share Posted February 24, 2017 (edited) Gents, I know the Sbooster stuff in not state of the art, however if we refer to their power supply that they offer for the Mytek - https://www.sbooster.com/botw-pp-eco-12v-132v/?language=en - this unit is rated at 28 watts max so my simple maths suggest @12 volts = 2.3 or thereabouts. Not wanting to butt my nose in but it is useful to look at other commercial offerings to see what they consider a sensible spec'. Of course, if Clay can get more juice out of his unit that 2.2A then that's great - you'll have some headroom. We referred to the Sbooster stuff when Clay made me my powers supply for the then newly released Auralic Mini. By referring to their spec' we had a ball park as to the spec's that Clay's power supply should meet or exceed. Result = brilliant sound and never missed a beat. Just my 2 cents. Please ignore if you wish! Edited February 24, 2017 by scumbag Link to comment Share on other sites More sharing options...
Gieseler Audio Posted February 24, 2017 Author Share Posted February 24, 2017 Andrew, actually I do a 12v 4A version so that should do the job. I looks the same as the standard unit but has a nice external potted 12v 6A transformer so after regulation & loses is good for 4 Amps DC. Cost is $350 delivered 1 Link to comment Share on other sites More sharing options...
a.dent Posted February 24, 2017 Share Posted February 24, 2017 Thanks @scumbag. Clay, I'll take one of the 4A ones. PM sent. Link to comment Share on other sites More sharing options...

Suopermanni Posted February 25, 2017 Share Posted February 25, 2017 Linear PSU still going strong! Really does add something to the DAC I'm using though I have no idea why or how. 1 Link to comment Share on other sites More sharing options...
a.dent Posted March 14, 2017 Share Posted March 14, 2017 Hi Clay, I just want to say thanks for the excellent 4A PSU I'm using on my Mytek Brooklyn. The 4A seems adequate. No obvious dropouts. The SQ is definitely a step up from the SMPS inside the Mytek. Well done. And at a price way better than anything available from eBay.

Gieseler Audio Posted March 14, 2017 Author Share Posted March 14, 2017 (edited) Hi Andrew, thank you for the kind words. Good to hear it doing the job. The 12v 4A version is a new design with some high specked parts so it nice to know you can actually hear an improvement over a SMPS supply. It uses a new layout with high efficiency low rfi emission dual Schottky diodes witch are bolted directly to the case for cooling. These work so much better than the usual block rectifier you see in most PSU's of this capacity. I will post a photo of the pcb tomorrow when I get to work.

tastimp Posted March 14, 2017 Share Posted March 14, 2017 Another very satisfied customer here. 2 x 12V PSU's sitting side by side in my loungeroom for my SoTM SMS200 and LH Labs Pulse Fi dac. Thanks Clay!Matt 1 Link to comment Share on other sites More sharing options...
Gieseler Audio Posted March 15, 2017 Author Share Posted March 15, 2017 OK internal shot of the 12v 4A version. Schottky diodes & regulator are mounted to the aluminium case using 3mm screws into tapped holes which gives excellent cooling. The diodes only run luke warm as they have super low forward voltage drop. It is a bit of a squeeze fitting in the main filter cap but it just makes it. RC snubber filter on the transformer secondary & a common mode choke all help to reduce any incoming noise. Link to comment Share on other sites More sharing options...
a.dent Posted March 19, 2017 Share Posted March 19, 2017 Hi Clay, I've been thinking about using one of these 12V 4A PSUs inside my server case. You may remember I've asked you about this before. I want to put the tranny in the case as well. If I take the back and top off like in the photo will it overheat ? Also I notice the jumper for grounding the case. Should I put that jumper in if I screw it to the server case? Link to comment Share on other sites More sharing options...
Gieseler Audio Posted March 20, 2017 Author Share Posted March 20, 2017 Hi Andrew, yes should work fine like that & no problem with the cover off. I put the ground jumper option in but but haven't tried it. What it does is connect the negative output of the PSU to the PCB ground plane & also the case. If your server case is earthed when you screw the PSU down it achieves the same thing as the jumper no no need to add the jumper. Link to comment Share on other sites More sharing options...
