TopBand: beverage transformers

[i4ewh@sira.it (Paolo Zaffi)]

I'm working around a 250 m beverage, and winding with the same transformer,
but I'm using a very old blue toroid discovered in my scrap box.  It is the
same, or a grey toroid is absolutely required?

Thanks for your patience, good luck in the pile-up!
