So I took this receiver apart and found two of the output transistors where blown, the main fuse, and two smaller 6.3 amp fuses. I replaced all and plugged it back in and fuse didn't blow standby power came on. So far so good, but when I pressed the on button the main fuse blew along with the two 6.3 amp fuses. So I took back apart and checked most everything. Is there a logical way to narrow this down. I will circle what fuses and transistors I replaced in the pictures. Thanks for any help I am learning alot!!
