Steve was awesome enough to reach out via PM and we dicsussed the schematic and he gave me some great input.

For those who are working on this same issue, my case the amp was popping the power fuse on the back of the amp. Replaced the a970 transistor, r314 and R337 4.7k with 1 watts and replaced some caps as well. Venturing into the output transistors I found one bad 2sc5200 so I have a replacement coming.

Since i have all of the output transistor out, I will also redo the thermal paste for them and the thermal pads on the heat sink.

Once I have the new 2sc5200 in I will update all with the results.

Mike
