This little fucker.

I finally screwed shut the A500r3 I had around for ages now.

Then I re-tested it. And I heard a faint tik.

No video, no life. Erratic behavior by the power led. 3 hours of troubleshooting and found that the video section is powered through this resistor, and that the voltage after it is also used to pull up the /extclk signal on the Agnus. That wasn't pulled up properly, so an intermittent clock got to the CPU.

This resistor cracked.

On the bright side, with the Mobo out, I finally got around swapping the shoddy socket on the Agnus.
