Parts for Pultec style EQ (power transformers).
I'm almost finished figuring out how to build and where to get all the parts for Gyraf version of Pultec EQ.
Now here is where I have my doubts: transformers.
Originally I wanted to use 2 toroids for power transformers, but I have done some reading and found out it is not the best choice for audio. A lot of people tend to recommend EI, C or R cores.
Basically, the advantage of toroids are higher efficiency, size and lower EMI.
Not sure if these advantages are relevant for me, because I was planning to put the transformers outside the enclosure anyways. Size is also not an issue.
It seems they are more vulnerable to mains noise, which would be bad.
But then again - does it matter? There is only 1 buffer, which adds no gain basically.

So either 2 off the shelf toroids or 2 of these R cores.
What would you recommend? Maybe something else?
