Hi Ok, quick intro to Rb standards:
On an Rb you have a light bulb. It’s a really weird bulb but a bulb none the less. On most (but not all ) designs the bulb has a finite life. Various improvements over the years have stretched out the life. Just when which outfits did which improvements …. who knows …. Rb’s need to run hot. They have a couple of heated zones inside the physics package. Heat and electronics are not a good combo. Various designs have issues on the stuff inside the hot zones. In addition to all this, they have crystal oscillators that drift. Once the oscillator drifts far enough, the device isn’t going to lock up. That’s a quick, very non-specific to your unit, list.
