I replaced the Vert o/p with a LA7833.The orginal was a LA7832.Also the 75 volt
zener.Checked the caps,IC982=9 Volt reg.When I turned set on it blew a hole in
the LA7833 & unit will not turn on.Removed the LA7833 & unit still not turn
on.Checked the SMD transistor's Q921,Q922,&Q924.Replaced the STRS5708.Checked
the PC901 &902.Need a print or tips for this unit.Where does the 5 volt
orginate from ?I tryed to get a data sheet for IC401=TA1242 &
IC701=MN1876478JZT1.....TIA....
