SO, one of your transistors is fully open and another is fully closed. Namely, Q10 is closed. Which means that Q4 is fully open.
This sch with all transistors being OK cannot work like this. Make sure output AND the ones before them (Q6 and Q8 ) transistors are intact.
Q: how do you check them transistors?

IF can wire size and Rubber mounts?

| Renovated Radios do carry what you need.
