The VR-509 looks identical to my krf-v7030d from Australia. Thanks to the 2 guys who posted web sites with pics that are active even now, and everyone else for their input. I was also able to fix my amp by resoldering the pins.
I agree with as someone also mentioned that it is mainly vibration that causes the cracks because of the long pins that go to the IR eye.
The main thing that didn't stress me too much about not having remote control of my amp for 6 years is that everything could be controlled from the front bezel, unlike more modern products or lower-end models where you lose the remote you're screwed.
