Is it worth to fix these old amps? The advantage: nice small boards. Q12 to Q17 sit on a separate PCB the transistors mounted on aluminum profile intended to be mounted on heatsink. The original transistors are either unknown or discontinued for many years thus the simulation is with available and reliable Spice models. I am unsure whether the Wilson mirror (?) makes sense at all.

Replaced EF drivers possibly dead from breakdown or second breakdown the power 2N6030 2N5630 seemingly ok. possibly operator error caused failure. Output short. Still don't know what designer "had in mind" with the Wilson mirror but will keep it as bass driver in active speaker
