stephenashworth Posted March 25, 2023 Share Posted March 25, 2023 Hi There, I wonder is anyone can help? My Helix floor's internal switching power supply (psu) has blown. Specifically the switching diode on the psu module has fried and having removed the module from the chassis, there is a rather unsettling rattle on the board I can't quite locate. Fortunately, the psu is an open open frame module by CUI (VOF-65-12), unfortunately, this module has been discontinued and is no longer available. Presumably line 6 are no longer using this module in new Helix's, so does anyone know what module they are using now so I can track down an "approved" replacement? Fwiw, my Helix is one of the early ones and I use it daily, it is switched on for about 16 hours a day as I mainly use it as a DAW. Many thanks Quote Link to comment Share on other sites More sharing options...
PierM Posted March 25, 2023 Share Posted March 25, 2023 Dont know if it's being used in the Helix, but a direct substitute for the VOF6512 is the ECS65US12. Id contact support for a confirmation, even if they share exactly the same specs. https://www.xppower.com/portals/0/pdfs/SF_ECS65-130.pdf https://www.newark.com/xp-power/ecs65us12/power-supply-ac-dc-medical-12v/dp/67R9479 1 Quote Link to comment Share on other sites More sharing options...

I also found this... https://uk.rs-online.com/web/p/switching-power-supplies/2216388 which is available and seems ok but the power connecter is offset. I think it would be fine but I would rather get a line 6 approved replacement. I'll contact support as you advice, hopefully they will be happy to share the Information I need to get my gear back up and running. Quote Link to comment Share on other sites More sharing options...

Unless support advises otherwise, my fix is in the bag! Thanks again. 2 Quote Link to comment Share on other sites More sharing options...
stephenashworth Posted March 28, 2023 Author Share Posted March 28, 2023 Ok, for anybody else who faces this problem. The news is good, the ECS65US12 works perfectly. The holes of psu circuit board are a little tight for the supporting pillars but it went on with a little effort. Everything is now working fine. Thanks to PierM and Datacommando for their support!!!! I hope this helps someone else if they have this issue. Although this is a relatively easy repair I would recommend this fix only if you have some experience with replacing boards and components. If you have built or maintain your own PC, this fix would be a piece of cake. 2 2 2 Quote Link to comment Share on other sites More sharing options...
PierM Posted March 28, 2023 Share Posted March 28, 2023 Glad you solved. Honestly, I was pretty sure would have worked out (specs are the same, with much better protections than the legacy model, and much better idle consumption). Yay. :) 3 Quote Link to comment Share on other sites More sharing options...

Came home today and im like you have my Helix turned on a lot of hours as I use it for my soundcard and also sometimes forget to turn it off overnight. Mine is also and early version bought early in 2016 and is in daily use. Came home today and house was all black, main fuse had been flipped. After a while I go to my PC and turn on the Helix (its connected to a remote outlet so the outlet hadnt been turned on after i flipped the fuse on again) turned it oin and only the small lcds flickered on the unit, smelled a bit burnt electronics in my room. After a while the small lcds displyes the labels, big lcd is black so i fired up HX edit and it finds the helix like usual but small lcds are flickering, starting a backup and halfway through the helix makes a popping sound from the power side and house turns black again. Opened it up and it's the same with mine, diode is burnt etc so im guessing power supply failure, i mean it happens with PC's as well etc. Its now all dead and black so im ordering the PSU you wrote and see if it helps, its 8 years old so warranty is out anyways. To bad tho the price on these things have risen 1/3 since i bought mine haha. 1 2 Quote Link to comment Share on other sites More sharing options...
yoMuzicMan Posted September 1, 2024 Share Posted September 1, 2024 Hi. @rudeez, I have the same issue with my Helix Rack. It looks like the same power supply posted in this disucssion. Did you get a new power supply for your Helix? If you did, and it solved your issue, would you mind sharing a link or relevant info of what you purchased? Thanks, Ron Quote Link to comment Share on other sites More sharing options...
stephenashworth Posted September 2, 2024 Author Share Posted September 2, 2024 Hi Ron, I can help you. I bought my PSU from Farnell. Below is a link and all the spec sheets are there. For me it worked flawlessly and I haven't had a problem since. All the best with your repair, I know my heart was in my mouth until I made the change, switched it on and all was good. Best of luck! https://uk.farnell.com/xp-power/ecs65us12/power-supply-ac-dc-medical-12v/dp/1821421?CMP=e-email-sys-orderack-GLB 2 Quote Link to comment Share on other sites More sharing options...
