Is there a way around this besides using a separate enclosure?
I originally built this pre using an 18VAC door bell transformer and it worked great (very quiet) without this proximity effect on the input. This is not at all the case with the large toroid I'm not using. I may have to go back to the door bell but I wanted to see if there's a way to block the field inside the enclosure to where it won't be picked up by the input tranny.
