Yamaha Amplifier Warranty Issues

My Honda dealership has a part backordered now going on 8 weeks. 

We live in a different world now.

This is when you get your dealer involved. He's your advocate with Yamaha, and should convince them to either replace or promptly repair the component. You are his customer and he has every incentive to take care of you.

There are still supply issues from the pandemic that are affecting many electronics companies — nothing they can really do about it and not their fault.  Replacing with a new amp is simply unrealistic.  I’d suggest just being patient.  Yamaha is a reputable company and I’m sure they’re doing everything they can to get the parts asap.
