Vinyl Savor 6CB5A SE Amps?

Input transformer

Quick question for Thomas (or any one else who has built an amp using his design).
I am just about finishing a 6CBa amp based on your design. I wish to use an input transformer to provide flexibility of RCA or balanced input selecting one amongst the choices available in my box. Pl advise which of the following will suit best :
Magnequest B7 10k:10K ( Hi Nickel)
Altec Bridging 15k:15k
Lundahl LL1540
Lundahl 1531

Tempted to use Altec because of the octal pin config for the base.

Cheers!
