Studer Console Output Transformer

[Fezzle]

Hi folks,

I am looking to replace the output transformer's on my Studer console's 2 master channels, and was hoping anybody could help shed light on if its an easy swap or not, + any potential issues.. any input most appreciated. I'm not much of a tech at all so don't have any test equipment, but would like to go ahead if there is little margin for error.
I've been looking at the PCB mount Jensen models 1:1 line output models, as I would like the cleanest and most linear (phase, distortion etc) solution...
My main question is that my current Studer transformers are stated as being 1: 1.12.. so its a little off a straight ahead match.. Would this be cause for concern when putting in a new 1:1?? Is that small difference probably there to add gain or something?
Also aside from this, are there any other specs or electrical parameters to look out for that could screw me over..?
I would have thought the main thing is that the replacement is being fed by a near zero low impedance, and my output op amps are doing that.. though, there may be more to it

Thanks and look forward to your advice.

I am installing a Studer Vista8 in a studio currently, they are not very friendly to work with, at least without a maintenance contract. Question, why replace them? If they are working then leave them alone.
