Looking for help with a Rogue Magnum 66 Pre

I'm fixing one for a friend, and have a question about one of the transistors that was replaced with an NTE part. A 3.5A fuse blew, and a prelim check of a T0-220 transistor shows a short. It was replaced with an NTE 171. Would love to find a schematic. I have a drawing for the 66LSR version but they are different.

THX in advance,

Jon
