Hi Johnny, sorry to hear you are having problems with your amp. I just repaired an xti1000 with the same issues. Q133 & q132 shorted, D187, D188, D189, D190 also shorted. But also found one output transistor shorted from collector to emitter. I would double check the output transistors. I replaced all parts and I am back up and running. Hope this helps.
Good Luck. Frank.
