No, R21 and R22 where connected. after powering only the input stage there no current flow even when R12 and R20 are connected.
Sadly i dont have an osciloscope, but i dont think its oscilating since im using a linear power supply but i will try to add capacitors

Just to confirm I understand correctly, with R21 and R22 opened, but with Q15, Q16, R12, R20 installed, supply current is low. But connecting R21 and R22 to their inputs triggers excessive supply current?
If so, maybe rail bypassing will help.

Im going to bed now thanks for all the help, but im not sure i want to countinue this "project" since the problems really dont stop or atleast i want to take a big break from it. Again thanks for all the help
So uhm this is kinda embarrasing.... So basically i put the npn transistor in the place of the pnp one and so on.... and all of this happened because i was looking at google for pinouts and saw this missleading image even tho the tip3055 is a NPN. (i used 3055 and 2955 instead of the 2sc5200 and 2sa1943 since they were cheaper and this amplifier is meant to be low power like 45-50W)
Also i got confused by this picture since the tip2955 is the an PNP
