You likely have other parts blown as well, but Q3 (MJE15033) AND/OR r8 (1 OHM/0.5 Watt) are blown. I suspect that Q3 has a base-collector short and you will find several of the output transistors are fried as well Q4, Q5, Q15, Q16. I suspect that the Zeners D14, D25 may be blown.
When restarting this, put a 100 Watt lampin series with teh 120 volt power to limit current and avoid destroying freshly repaired parts due to a few bad ones not found.
