The Gardners transformers were wound for the Williamson design and have 8 separate secondary windings. !5W will be more than loud enough... and it will sound much better than your Leak Stereo 30 and any other early transistor amp that uses capacitive speaker coupling.

I would be inclined to use new EL34B's (made in china) as they are pretty cheap, reasonably reliable, and will use the same connections as the KT66.

The power transformer should be OK for HT current but you do not mention the LT windings?
