SPARCClassic won't turn on, clicking sound

Hello all,

I've just plugged in a SPARCClassic to 240 V 50 Hz AC (brought it with
me from a 60 Hz country).

Despite the power supply being rated for this, it won't start in the
traditional sense of the word.  The speaker makes a clicking noise
when I press the power button and until I turn it off.

Inside the case, everything appears intact...  It was working when I
packed it before moving, although I recall the switch "sticking" (a
series of clicks before power off) a couple of times when I turned it
off remotely.

On cctalk, a list member suggested that the power supply was taking
its last breath. If this is the case, does anyone know a source for a
cheap SPARCClassic (or similar lunchbox) or simply a working power
supply (300-1101 I think)? I'm in France.

Thanks,
- Alex
