You have the schematic... you know the rails... If you assume that the output will 100% swing to each rail... what's the answer?
OK, I don't have the schematics in front of me... I'm actually working... so I figured I'd ask a simple question. I didn't expect the Spanish Inquisition.
^ You're on the internet, typing in a forum that has the schematics posted literally in the first post... you've been waiting for this project for a while...
So, I figured you'd either A ... already know a little about it... or B simply look it up and try to learn for yourself...
You know I joke... with snark.
No, it will not drive a typical F4 to voltage clipping.

Cardinal Ximinez : Nobody expects the Spanish Inquisition! Our chief weapon is surprise, surprise and fear, fear and surprise. Our two weapons are fear and surprise, and ruthless efficiency. Our three weapons are fear and surprise and ruthless efficiency and an almost fanatical dedication to the pope.
old, qwayzee all my life and now even more..... but there is now also strong Deja Vu for me
not just question asked but me also replying to it

Thanks, I remember that.
Looking at the schematics... version '23 v3.
sch 3 of 4 : I see = -IN/5, +IN/5, -OUT/5 and -OUT/5.
should these be IN/3, OUT/3 ?

clarify/post exact schm page you're talking about
practically, speaking of nomenclature of inputs and outputs - all you need to know is on pcb and it is same on schm
what you see as "flags" at xformer itself - ignore that - those are names of particular nets in circuit; tool used to connect what's needed between different pages of schm
so:
no.

Then, in the balanced schematics provided in the first post, I see four slides. Slide 3 calls out -IN/5, +IN/5 and so on... at the Edcor_pc600
And slide 4 calls out +IN/3 and -IN/3 as well.
There is no slide 5 of the balanced schematics, there is for the SE... I think the sheet 3 of the balanced schematics is either wrong or there is a missing sheet 5 for the schematics of the balanced design.
I traced them...

and, after my explanation - how those flags are of any relevance to you?
number after dash is not for "page", it is flag instance of same net

Oh.... I was chasing them across sheets. Thinking the number indicated the sheet not the instance. OK then... I spent quite a bit of time trying to follow those.
So, the Iron Pre makes for sharp horns. It can drive these horns through the grumpy gates of Aleph classic driver stages, which is a thing, and a sound imo. After hearing some classic jazz played on a classic system this weekend, I'm thinking that sometimes, maybe classic jazz should be played in a way that makes the horns sharp. If you have an Iron Pre, and an amp with cojones, may I suggest playing some sharp horns, just for fun.

Sharp as in forward, prominent, long decay, like the sibilance in vocals and hits to cymbals that retain loudness and trail off for a bit after the hit. Rightly or wrongly I've been associating these sounds lately with odd-order distortion, or rather with systems that likely don't produce a lot of even order distortion.
Here's the rest of the dial. Note if this were mine, in my system (ha!), I would have backed off the treble even further.

Last week I found a long sought-after Denon PMA 850 on eBay “for parts, not working” for a fabulous price.
Some contact cleaner and poking about and it resurrected itself. I’ve been using the Iron Pre on its main-in, solely as and amp, bypassing its whole integrated switchery front end (three, count ‘em, three phono inputs!) and wow, is this 45 year old (the amp, not me… I’m older still) is raising my eyebrows. A lot.
Let the Iron Pre handle things and review your amp lineup. DIY, commercial, old and new, a good signal in is a good signal in.

just matter of wiring appropriately pair of RCA/XLR
as done in 90% commercial products
if you want it properly - insert OP buffer, feed it from IPre reg

Yes, I would want both balanced and SE outputs. Maybe we need an add-on daughter card but I don't know what to do with the chassis.. it just looks quite good.
OTOH, I got enough preamps... maybe I should not hook up the RME AD/DAC into the Iron Pre and use it into the Conrad Johnsons.
Hmm.. the RME ADI-2 Pro has both balanced and single ended outputs... so I could hook it up as a tape deck on the CJ ( running SE IO ) and as an Aux into the Iron Pre (running the balanced). Yes... that would be awesome. Imagine, TWO preamps required to run the stereo.
I'm set. Made my life more complicated. I'm happy.
