I have a Onkyo tx-nr509,goes into protection mode and will show ever so briefly sp wire error code.I have read and researched all threads,videos and i seem to understand some transistors and or channels have shorted.I think one resistor is bad it would spark when i powered up the receiver,my problem is it is 2x .22ohm resistor which has a common pin in middle and two resistor package.I could not find such any more so received two .22ohm 2w resistors,but they only have two pins.my question is how to join these two resistors so they have a three pin common ?Thank you for all your help.One more question in one of my pictures it seems that there is a large transistor,is that what it is?

Look at the resistor symbols printed under the old part on the pc board. That is how it is wired inside. Nothing fancy, just two resistors in series. Shove the two new ones together so they touch, and twist the wires together in t he middle. That results in your three leads.
If that resistor died, it casts suspicion on your power amp IC.

Thank you for your reply,I tried this by twisting the two together making three Leeds,it got super hot almost smoking,must be something im missing,Im a beginner trying to fix this out of warranty amp ,seem stupid on this forum for some people what is a amp ic could it be what is causing the problem ????
