They might be interstage transformers, similar to the one shown in the picture below.

Renewed, the AR amp is a good stuff.
No idea of the cause of noise. Leaky capacitors ?
I can send you the schematics if you need them.
Just send an email named "AR amp".

Thanks for your reply.
The noise come from the phono trap: i'm using the AR with a Dual 506. On the other connect it is still.
