^ That applies only to the boards marked "Iron Pre SE - Zen Mod Labs 2023". Just for double/triple verification, make sure your boards are marked 2021 and/or that they're not balanced boards.
Edited to add for clarity -
The only boards that applies to look like this... I updated the first post with the exact wording on the boards. Thanks for asking!

UPDATE FOR "THE LIST"
Jason has graciously agreed to help.
There are changes to what I posted before, so please read carefully. This will be much-much easier to manage.
This will open up the 'closed' purchase to all Greedy Boyz past and present and save all of us potential confusion and work. We've received a few comments re: purchase limits. The hard code for reviews has been removed. Just please buy what you'll build, are planning to build, or are giving to someone to build. Act in fairness. We didn't mean to be 'restrictive'.
I don't use GMT very well, but here goes...
In approximately 12 hours, which should be... 10pm GMT. 2200GMT I will post a password in this thread for everyone to use.
How will you use it?
Q - What if I was on a list before, but missed buying what I wanted to buy or just want one more for a 'friend' 😉?
A - Use the password you were previously sent or use the new one that will be posted later today.
Buy what you'll build, and have fun!
Enjoy the tunes,
Patrick

My boards are marked Iron Pre SE Zen Mod Labs 2021, so I will disregard the warning and go with the + on inside and outside of cap as positive and thanks again @ItsAllInMyHead
And should i now follow the silk screen to mount the cap or go with the first post correction to reverse the cap with the silk screen?
you have 2 options:
1. orient cap as per symbol inside polarity sign
2.orient cap as per symbol outside polarity sign (which I manually added)
3.orient cap contrary to symbol inside polarity sign
4.orient cap contrary to symbol outside polarity sign (which I manually added)
5.do not mount cap at all
first 2 are giving you same outcome - cap will be oriented properly
second 2 are giving you same outcome - cap will not be oriented properly and it will go to ghosts soon enough, with or without damaging something around
fifth - everything will work pretty much the same as with properly oriented cap in place
see how good at math I am, almost as in logical line-up of things

as final cap in relay PSU?
as a matter of principle - use cheapest quality cap, or not use it at all
on the other hand - nothing is preventing you to mount outboard Duelund solid cap

I don't implement any relays in my build 🙂 .....but good to know for others....
I would need a larger chassis for mounting Duelund. The factory is not far away. They bought equipment from the Danish Jensen Capacitor factory whey they closed 1-2 years ago or so......

Time goes fast it was in 2019......

Even that it is a bit "off topic" it is interesting to watch the old "Jensen" machines still be used to make foil capacitors:

So old Jensen factory still a bit alive.........so how can we use those in Iron Pre.......it has no coupling caps. Even jfet buffer to Cinemag is "without"......

Blasphemy from ZM !!
I knew that I missed something ........ I've cut you all from so important phase in building - voicing it with appropriate caps ........

^ Contact Modushop directly. I haven't seen prices yet. People that have purchased them may choose to share what they paid.
Paid 269 Euros ( I think it was just under $300) for the first one (including shipping to the US)... no VAT if you buy outside of the EU.
Trying to get a second now... my son is gonna get a great Christmas gift.
Just received my Iron Pre SE kit in the mail. A big Thank you to ZM and the diy team. Looking forward to working on this.🙂
Already did....for the Sissy SIT R.3 kit!😊. Unfortunately, still in the bag and untouched🙁220E to Modu, 250E to me, and 20% IVA on top of that

Here's what you need to order... tell Giancarlo it's for an Iron Pre and he'll know how to finish it.
Heads up, I think they're still on their summer vacation.. Euros and their August.

Iron Pre Sales Are Now Open To Everyone!
In order to give those that have been following the project, but may not have had the opportunity to get on the list or order what they wanted, anyone can now go in and order what they'd like. I do not know how long the remaining stock will last. We'll let this go until they're all gone or it seems that all the folks following this thread have gotten what they want. No more than 3 or 4 days.
Here's what to do -
Clever, right?!
That's it! Your store account now has access to the Iron Pre.
Buy what you'll build or know will be built.
Most importantly, have fun, and enjoy the tunes!
