If T4 1-2 and 3-4 were symmetrical I would think it would be okay. However, they are not symmetrical as 1-2 has 2 turns and 3-4 has 3 turns. Sounds like you should unsolder it and try installing it the other way. It may be easiest to cut the bare wires (5-6 and 7-8) before unsoldering the green and white wires. You likely have enough wire leftover to make 5-6 and 7-8 again, but not 1-2 and 3-4 (I think I had enough to make 1-2 again if neccessary but definately not 3-4). Correct installation of T4 should improve your output power.
If you wound T4 as a 2:2 ratio for better efficiency at 5W then it would likely be okay (note on the schematic for T4), but since you are complaining about not enough output power you should unsolder and install correctly, then play with alternatives later after you are satisfied with performance.
