This PSU and Protect circuit ca be used with any amplifier. Short-circuit protect based on Tandberg schematics is 100% efficacy.
will it be ok if i use 24-0-24 transformer?will the clip indicator,short circuit protection and dc protect work correctly???

apex,
this design is +/-50 but i need replacement
bd139 MJE?
bf420 MPSA?
and i'd rather make 4 pairs of output
should i make .22r resistor .33 or .47?

I'm not a big fan of solid state, but I have some questions!
I do not understand why you have C2 as well as C1.
What are the big 0.22R resistors for?
What is the loop feedback gain/amount?
What is the crossover distortion with the loop feedback removed?
I think you need a bias so you can also run in class AB (my opinion)
Why is there no bypass cap for the zener of the driver circuit?
Why is there no Zobel network (LC) on the output?

If you want 4 pairs of output I sugest you to build this amp:
