NAD 7240 Receiver Totally dead part 1 troubleshooting

I would have liked to have finished this one, but NOOOOO. Even though the parts are local,I can no longer go and get them, because some idiot didn't follow the rules, a complaint was filed and the city shut down the parts counter. Mail order only now, so once the parts get here in a few weeks this one will be back on the bench.
