DX Amplifier my version public

I builded this in real life and it works great!!! But it needs more work. First i have to change all the caps with new ones, ech a propper board for it and change the power supply with a 2X30VAC 300W power supply (at the moment it's with a 65VA 2X20VAC Power supply form a old tv ) hopefully it won't blow in my face at 2X42VDC. And not killing me will be great :). I am only 16 and I still consider living. However when my bias was low ( almost in class B) the output transistors got hot like in a class A amplifier, and yes I did put the bias transistor on the heatsink so that it gets worm form the outputs and start to conduct more so that the outputs don't overheat. (80-90C!!!) But it didn't work so i left it at 770ohms like the resistor in this circuit. The 90kohm resistor should be 18k but EveryCircuit is like "Sorry bro cannot find solution". Hopefully this time it will save cuz I made this circuit before and when I saved it it disappeared and when I started building it again EveryCircuit crashed :/ EveryCircuit hates DX amps :-) https://bgaudioclub.org/album.php?albumid=119 the last two are p3a and a 45W class B amp
