Default Re: Marconi TF 995 B/5 weird waveform need schematic

Dear all,
I've managed to get a B/5 version schematic. Big thankyou to Paul Jones.
Resistors and 'things' (that I can get to) are close to marked values.
Isolated external influences.
I've tweeked T2 and T3, amplitude peak for mid scale, but still getting the falling level on triple output.
All other stages are good.
see image three.jpg
Can't see the wood for the trees.
How do I improve the waveform
regards
