i have used a trimmer in R5 (25k) and R8 (10k), i apply 48v and measure R7 (2.2k) with volt meter.
I tiddle R8 until i have 4.8v at R7 and then check voltage of both T1 (4.69v) and T3 (3.11v) source.
i now have semetrical waveform

Interesting.
So you “tiddle” (I guess trim) R8 ?
And you have 4.8V at R7 ?!? I’m getting 40,9V at R7-C7-T4 junction.
But what about R5, did you have to adjust it too, or left it at 13.3k ?

Well done anyway.
