HI all
Amp had shorted outputs changed them and the amp is working but there a resistor in-between output terminals and power terminals that is burnt. I would like to know the value of it. It is connected in-between main power ground and speaker ground.

I don't have anything for this amp and it doesn't look familiar. Maybe someone else will know the value.
That said, it probably won't matter much. A 1k is commonly used. Orion typically used a 120 ohm but I don't know how much (if any) of this amp is like the older Orion amps.
You should twist the transformers to see if there is an intermittent short. On large amps, this resistor burning can be due to a speaker wire shorting to ground but I don't think this amp has the power to do that.
If the non-bridging speaker terminals are directly connected to the RCA shields, I'd check the shield ground on the head unit.

Hey if you had blown tip35/36 outputs, check my thread here. I found some 100 ohm resistors blown open deep within the drive circuit after output failure.
