Part 2 Onkyo TX-NR636 Intermittently shuts off. Corrosion? Customer repair? It's fixed

A nice Onkyo TX-NR636 came in and the customer says it shuts off intermittently. Let me tell you, it had some carnage on the driver board. Luckily I found an almost identical model at a thrift shop to harvest parts from. All but 2 transistors on the driver board were bad. I replaced 9-transistors, 3-surface mount resistors, 8 fusible resistors, and 1-shorted capacitor. I did get the tuner operational also. I accidently shorted my test probes out and blew up the surround channel which I rebuilt off camera, but all is well again.
