Cinemag transformer placement; before or after the attenuator?

[KT]

Hi, all.

I'm finally starting to build my LM3875 integrated Gainclone based on the AudioSector boards I purchased some years ago.

I also got a set of Cinemag line transformers that are designed to sit in the signal chain at the inputs.

My question is that if I'm setting the amp up as an integrated amp, with a 50K stereo shunt attenuator, where should the transformers be placed?

The positions that come to mind are: 1) in-between the attenuator and the amplifier boards (so behind the attenuator, but in front of the amp boards), or 2) behind the source selector, but before the attenuator (so after the output of the source selector and before the input of the attenuator).

What it boils down to is should the transformers be placed before or after the attenuator?

Thanks for your help!

Set it up so that the input source directly drives the primary side of the transformer. Do attenuation on the secondary side.

Great. Thanks for your help!
