I recognize this is hardly worth the bother to the others building the Iron Pre kits however, I bought a few extra Fujitsu Takamisawa RY-24W-K relays (from Surplus Electronics) and CK1060 rotary switches (from Newark) as a sort of impulsive reaction to having to pay shipping from so many different suppliers. But I really don't need to stockpile more stuff.
If there are a few folks in the US who would like to buy a rotary switch and some relays, message me. I would just charge exactly what I payed ($1.50 per switch and $2.50 per relay) plus First Class Mail. You will save ~$16 on shipping compared to buying them directly.

All the extra parts I have are now spoken for. I got locked out of responding to messages but I will try to follow up with everyone when I can.

Darn! I just sent a PM. No need to respond.

Had a wonderful visit with GianLuca today and was happy to see this waiting to be shipped to a new lucky customer…

Best,

So just wondering is this something I can order from the DIY audio store? I'm not seeing it if it is??

 

[william2001]

Well it looks like the timing on diyAudio Store kit and chassis availability is "TBD" if I'm understanding the post #1 updates correctly.

Getting closer to a first soundcheck?...

[Zen Mod]

you can ditch htsnks from mosfets

htsnks are for sissies, anyway

 

[cubicincher]

Yup!
I am the super-weakling-sissie-master...and server of the endangered species of Mosfets. 😉

 

[ItsAllInMyHead]

Looking good, Dirk!

 

[Zen Mod]

Hallelujah!!!

 

[cubicincher]

I couldn't resist - it's playing music...

Listen to some songs - although slightly tired. But as Zen Mod always says: sleep is overrated!

Super easy to adjust voltages and DC-offset before CINEMAGS.

Thanks, Zen Mod!

Good night
Dirk

Moooorning!
It was really so easy to adjust the DC-offset to 0.0mV (millivolts!) - nothing!

I put the Iron Pre this morning together with my 6-24 active crossover and the BA-3 poweramp (bass-mid) and the F5 for the highs.
Speakers are active 2-way with ScanSpeak Bass-Mid-woofers and an ATM (air-motion-transformer).
As short as I am listening - I can immediately say that Zen Mod did an excellent job!
If I listen to acoustic music, especially with stringinstruments (guitar) or to a piano (which is in my opinion often a challenge for amps),
the Iron Pre plays very exact and detailed. No harshness. High tones from a piano sound like a piano.
If a string swings out long like from a long guitar tone - great!
Room information in the music is also on a very high level.

ZenMod - you did an excellent job!
My Iron Pre will get a nice 'house'. I am thinking about a nice case.

I wish you will have so much fun building this preamp like I had the last few days!

Wish you all a relaxed weekend with good music
Dirk 😉

What volume controls are you using?

Regarding the glowing SQ reviews... Question- "What is the best VAS transistor?" Answer- "A transformer..." I forget who said it.. Reason I'm always trying to keep one somewhere in my signal chain these days..
