No, but it is good to have the PT rotated 90 degrees and positioned in-line with respect to the OPTs. .......
I suppose that menas OPT iron facing towards PT
But then OPT might radiate towards supply trafo instead, or maybe input
You don't need to worry about leakage flux from the OPT unless the OPTs are really undersized and will be driven well into saturation. Even then, distortion will be so bad due to the oversaturation that whatever leakage there may be will not even be a factor.
The thing to worry about is the PT. It is often driving into saturation due to the switching currents and so forth. Keep the PT as far away from everything else as you can, especially the OPTs and any input signal wiring.
