using 2 x-formers/psu, when to rectify?

[Christian]

I'm planning on using two x-former ( 12V out, 150 VA) in my new LM3886 based amp. I have to do this because they only have one voltage on the secondaries.

So, when do I connect the two secondaries to make ground, before or after rectifying?

Best Regards,

You can do it both ways, but after rectification with
a bridge on each transformer is preferred.

Oki!!

But, do I have to use 4 voltage-rails then ( with all the neede caps) or can I juste do it like this? ( whith only the two voltage rails and 2 banks of caps)

Looks fine.
