Know of any true bullet proof equipment stories?

Vintage Crown DC300A amplifer. Bought vintage amp last year for my son. The amp was poorly packaged and as luck would have it, was dropped during shipment to me. Part of the chassis was bent. It went back to Crown for a factory check and chassis repair. The drop only did superficial damage to the amp. Otherwise, even after 35+ years since it was built, still specs perfectly. My son loves it! I wonder if it would work under water, maybe as a boat anchor????

My comment is a little off topic, but picks up on a story similar to Hifixpert's experience about reputable companies that stand behind their gear. In my case, the equipment is an Audio Research VS-115 tube amp.

Yesterday in the late afternoon, while checking tube bias, it came to my attention that the bias voltage in one tube was zero. I immediately called ARC and spoke to Calvin Dahl. Calvin diagnosed the likely problem as being a burned out bias resister, which happens from time to time with tube equipment. Calvin checked the serial number of the amp and advised that it was still under warranty. He also provided me with the name of a local ARC authorized service technician.

The technician kindly agreed to check the unit and effect the necessary repairs IN MY HOME because the amp is a little too heavy and bulky for me to drag around. Two hours later, the tech showed up. The repair took all of 45 minutes to do (i.e., replace a burned out bias resister), and voila, I'm back up. Of course, the repair was covered under warranty.

I'm sure that other members can offer similar stories about their experiences. And maybe they should -- in another thread. But since my experience is so fresh after just reading Hifixpert post, I had to post my story too. Kudos to ARC -- and Bryston too.
