Yesterday, I played a bit with ground connection on those transformers. There is distinct difference between hardwiring the grounds (from inpu to output) and leaving the ground floating (not connected). While hard wiring softens the highs somewhat, floating the ground provides for more bright and etchet presentation. So try both, you might have stronger preference for one of them.
It is also strange, but IIRC, with my first version of those transformers (19 tabs only) I couldn't float the ground, it is possible with the current version.

That sounds exactly like the sound variation you can get from just about any equipment if you mess up the ground wiring...
Could you explain what do you mean by floating the ground and hardwiring it?
It might be the language barrier that I'm not sure what you mean.
Is one case when the ground for channels go separate side by side with signal,and the other way when all the grounds meet at one point?

It's quite obvious. With transformers you normally have the choice of separating grounds between primary and secondary circuits.
Bartek,
Check out the bent audio site at www.bentaudio.com.
On that site there is lots of informations on TVCs.
Go to downloads and check out the assembly manual for example - do a search in the document for "ground".

It means that the input grounds and outputs grounds are not connected together and the output signal is generated in the secondaries, with complete isolation from primary signal.
I'm not sure what it has to do with " sound variation you can get from just about any equipment if you mess up the ground wiring..."
It just two different ways of getting the ground signal, but why would one way be less "messed up" than the other?
Technically it has nothing to with each other; it was just an observation basen on the sound you described... Don't mind me, I've got a bad cold and are probably just rambling anyways 
Thanks a lot for explaining this to me.
Now it seems obvious.
I pretty much forgot you are talking about transformers here and more thought about how things are connected between rotary switch and input and output RCA's.

i just got the seiden switches (2 x mono) and they are miles away from the standard elma switches.....but also a bit more costly.
exactly what i was looking for and good service from bent audio too.....🙂

My 23-step ELMA switch really ****es me off...
Often I hear clicks while moving and one contact doesn't work 🙁

this knob looks exactly like the two i got from bent audio.....

Too bad your Seiden switch is too big for that chassis😉

well.........make me a chassis that fits the seidens - only xlr IN and 3 xlr's OUT for each channel......$$$ or trade.....?
🙂
cool homepage......! just saw it.
yes i will use two mono switches.....
but - let me contact you at your "work" and we might be able to design a box for the seidens......🙂
