Aye. Williamsons are very good if you can get the iron. Too bad you need a kid to tell the difference if you are most of us.

(edit) There still needs to be some consideration to harmonics as in all amps, and usually a small high voltage capacitor across the primary will take care of it (if it opens up, yup, tweeter toast!), along with the other common precautions such as resistors in series with, and after coupling capacitor, and resistors between screen grid and it's winding. I've seen 1K 2 watts used for this purpose a few times.
