725-1025-1425-2025-2925 on the primary and 48-66-96 turns on the secondary. Here it is possible to see that the 2.5W tap is almost in the middle, with 1425 turns on one side and 1500 on the other. This small difference could be a problem in some bigger amplifiers, but here it will just add up to the distortion.
