Just as it should be. This layout looks to be the best. I am still wondering exactly how I will layout my build with the chassis and volume control that I have chosen.
just for giggles, next time** twist your signal wire pairs and triples
if nothing else, it looks neater
**every proper DIY house needs to have multiple Iron Pre
It is singing!
I have had only a minor time in the morning.
What can I say, it is dead quiet, except if it plays music. 😉
About the sound shortly, it brings life to music.

How did he get up there?
Via the amplifiers? <-- maybe reason for the blue protection foil?
I know some cats can jump high but.......

you can piggyback properly matched pairs or triplets, getting more Cojones, so lower Rout
in which case 10R trimpot in sources will suffice
Dear Zen Mod,
Thank you for your answer!
So the formula is simple here: more is better.
There is a problem, even if you have some JFETs, there is quite difficult to find proper octets.
Despite of this, I have three octets, the first one is from the IP package I've bought, these are at about 5.5mA range:
The second, I've selected these with some patient work, at about 7.45mA.
These are playing now in IP, perhaps with a little bit more determination.
The third, I've bought some years ago from Alweit.
These are V type JFETs, at around 13mA.
I think these will be the final candidates.
I think I will not bother myself with piggybacking.

I almost forgot, that I have some JFETs from Jims Audio.
These are singing now in IP, at about 10.2mA.
More life, more punch and tintinnabuli.
I think, I will follow ZM'S advice with 10R trimmers and with 13mA set.
JFETs at 5.5mA are just for sissies. 😉

For the 3-pin jumper header on the Iron Pre SE boards, 'Fancy Boyz' can consider the 3P HEADER GOLD 15u single row from TE Connectivity - Mouser PN 571-5-146280-3.
It is gold and will guaranteed elevate the aesthetic of your board to the next level, perfectly matching the gold solder pads.
oh yeah, fancy
