Nice circuit have you listenet to the circuit?
What about adding a diamond buffer to the output?
Best regards

I have no idea, i have only ztx 1051, 1055 and 1149(pnp)...I found them thrown out in a bin at a factory i worked in the past at.They were doing lots of very high voltage power supply so they must have used these transistors as drivers in some old products along with the classical 651, 751, 851, 951...

A very interesting alternative is to use Jan Didden IV converter with a small change. just added a current source to increase the gain, the results are promising.

On Q4 you would want to add a connection between collector and base.

"Jan Didden IV converter" - where can it be seen ?
