Thanks. Made a separate thread for this because I was not getting any responses here. Went with the 3000 mA one for $25 less, because with only a few modules with incomplete power stats on Modular Grid, the entire setup in 9U 84HP was less than 1000 mA TOTAL. So the 3000 mA one should be fine.

Any experience on if the red line is correct on Erica Synth modules?

Hoping someone smarter than I can check my power and see if I'm alright. This is the theoretical power consumption of my finished rack:

1181 mA +12V | 677 mA -12V | 0 mA 5V

I'm powering it with a 4ms Row 35 whos specs are:

+12V @ 1.4A | -12V @ 1.25A | +5V @ 1.0A


I'm getting up there on the +12v rail and was just wondering if this will be a safe long term solution. I can upgrade to the Row 45, but I don't want to unless it's necessary.

Thanks!

I`m making my own cables up now, I started with a Known Good cable and copied it, checking it several times over and then giving it to someone else to check (2 sets of eyes are better), and I never make more than a few at a time so there`s no danger of complacency setting in.
Just need to put together a little test rig now, but all the ones I`v made so far are good and I`m using them.

It should. A trick to know where -12V pin is in a shrouded header is to locate the little tab. -12V should be left from the tab.
As I see in the picture yours is correct.

The only problem that you could have is the power spike needed when powering up all the modules at the same time. Once all the modules are turned on the continuous power should be fine.

-12V label is written down the connector. You should orient the red side of the power cable to that label.

you most likely burned out the fuse, just plug in a new one (it's in a little green box, there are even photos of it just a couple of posts above). I had to change the fuse on mine at least twice already

here are the recommended fuse ratings depending on which exactly PSU you have

I have some questions about using these multi connection ribbon cables:https://patchwerks.com/collections/euro ... ower-cable

My case is the Intellijel 7U 104HP Performance case. I've run out of headers to plug modules into, but still have more free HP in my case. I read elsewhere that you can use these multi connection ribbons to plug multiple modules into one socket.

All the modules I'm planning to use have combined power needs well below the total power the case's bus board puts out. So no worries there I think. But are there power restrictions for how much draw you can have on one individual socket? I did not see anything in the performance case's manual that addressed this.

Also, I read that using multi connection ribbons like this can sometimes introduce noise to your signal. Are there certain modules that would be better suited for a multi connector than others? Like should I not put my VCOs on these multi ribbons or other modules that are handling audio rate signal?

Does anyone have any experience with the Tall Dog skiffs? I believe the power supplies were designed by MIT students! Seems like a few accessories are needed to get up and running, but overall, seems like a decent deal for an expandable rig.

Its perfectly labeled. Can't see whether the header is shrouded, but just be sure that -12V connects to -12V on your cupboard. The red stripe is an indicator but you can't always rely on it.

-12V is down on your pic, it's labeled 12V with a white bar to the left.

Sometimes I just need each configuration in a graphic to remind me what pin does what. I trust cables because I would rather replace a module than do measurements on each one. Every time you get in a car, do you check the headlights and turn signals? Top to bottom, a pair of each: Gate, CV, +12, +5, Gr, Gr, Gr, -12. Right? Anyone not with the program I don’t have time for. Perfect Circuit takes returns and they are ten minutes away.

You have +12 and +5 pins reversed in your 16pin diagram. Check out this Noise Engineering post:

I have just put two together for 6u x 104hp with a 70W power supply (currently populated with only 24hp). It's my first experience with Eurorack, and I have all of a few hours' experience with the Tall Dog, but I'm impressed by the design, the build quality, and the flexibility, so far at least. If you have any questions, I can answer them.

I have a Bastl Ikarie and there's no definitive indication in the manual or on the module how to orient the 10-pin connector. There's a line on the board on one narrow side of the pin block that I'm guessing indicates –12V, but I'm not taking a chance. Hopefully the manufacturer responds to my query soon.

The line typically indicates -12v. So, as long as your power ribbon is built properly, and you line up the red stripe on -12 on both ends, you should be fine. If you want post a pic and we can double-check.

Thanks – Bastl got back to me and confirmed this. Though, thinking about it now, there's no indication on the Tall Dog case that the red stripe is –12V. There are no instructions except for the photos on Control's product pages.
