MagnaSine MS2012 Inverter Repair Rectifier Identification


Hello everyone, Bought a defective Magnasine Inverter MS2012  to repair. 12VDC to 120VAC , Low AC ouput under load  27VAC , dual fans dead,  replaced operate ok, No Fault Codes at all on ME-MR remote.Pulled FET board for component troubleshooting. ALL 20 FETs , no short but on the underside 3 physically blown and shorted rectifiers .I'm guessing they are of the MR750 Family but unsure which specific one , MR750 ,MR751, MR752. No markings what so ever , even under magnification. I'm hoping someone may know so am reaching out .
