Hi, Folks, If anyone's interested, I've started a blog with lots of photos, documenting my ongoing build of the Audio Note Kit 1 300B SET amp. If you've ever thought of building any kit before and want to get a feel for what it's like, you're welcome to have a look!
Reb, my only other advice is to make sure to not place the amp near anything that might be generating a strong magnetic field as a precaution.
If teh transformers had become magnetized, one explanation would be that they were in close proximity to a magnetic field of some sort at some point in their life, possible well before you ever met them.
