Here is a listing of 250 transformers that meet the voltage specs you 
requested (or close enough--primary 115/230 dual 12 V secondaries

You'll need to figure the power capabilities and the mounting.

Good luck!

As to the tone controls, I have no opinion other than if it works for 
you and sounds good, they it's OK for you. I think formal archival 
transfers would want a more rigorous approach which is why most of the 
equalizers seem to have fixed settings (up to 12, and there are 
different 12 on the two I've looked at).

Cheers,

Richard
