Those output transformers should work vey well, even with their 10 Watts power rating. The specifications for these transformers are excellent!
If you wish to operate at 10 Watts output, then you could utilize 325 to 330 VDC B+ in place of the "standard" ST35 operating parameter of 365 to 380 VDC,
and set the cathode current (bias) at 35 mA, for each EL84.
The power transformer should have steel end bells, or be toroid-wound, in order to prevent the magnetic-field coupling of the 50 Hz mains power on the power transformer's primary winding, into the output transformers, which would then create an "incurable" 50 Hz hum problem.
