Okay, I've gotten an email from another BBS user pleading for help.

They have just had their Mk2a upgraded to 64MB RAM (PCA board), knob & button LEDs, internal FAN with controller, and a full version of the digital out board.

A few hours later the onboard PSU appears to have suffered meltdown, and let out too much magic smoke.

Pure speculation on my part, as I have not seen the unit (nor done any of the aforementioned work on it). I suppose there might be a wrong value resistor on one of the various add-ons, drawing way too much current or something.

Or maybe.. maybe.. all of this stuff has finally exceeded the current draw capacity of one of the onboard voltage regulation circuits of the Mk2a.

Patrick, Hugo: Any idea as to the "spare" current carrying capacity of a stock unit?

This failed one also has TWO drives installed, so I'm guessing there wasn't much juice left over to begin with..

Cheers
