You must be new to tubes. In gear with tubes you always roll in new tubes first to see if one of yours is noisy. You only need to purchase 1 or 2 new ones (our own vintage_tubes is a great source for reasonably priced & fully tested tubes - tell him your problem when you purchase). Replace one tube (or one per channel) to see if the one you took out might be the offender. If not, swap the tube in the next position. Tubes have AC on their filaments and can be noisy.
