MC step up transformers diy advice

Hi - decided to make my own stepup MC from a pair of partridge vintage transformers - supposedly extremely good. Just one thing - is it preferable to box them separately or have both in same box. I thought I had read somewhere that discrete boxes were better re isolation - but haven't a clue? Thanks

Edit: project completed usng very high end parts and componets and now find myself making the odd unit for others - abolutely magnificent result!

 

Why not make it like this one?

 

I probably will! However I thought I had read somewhere that having each transformer in it's own box worked better - this one is clearly in one box as is the EAR MC3 - so maybe one box will do???

Anyone have a view?

Thanks Murray - v interesting. It would appear that most diy projects put these in the same box so may be the way to go.
