First test at the analog side , distortion figure is not bad but could be improved I think , I found that part of the signal ( -35 dBV ) is floowing back to the + 5 v supply througt the 2 ma biaising circuit
this graph shows secondaries in parallel , in series I have 1.3 v rms , distortion is about the same
