Hi Jan,

Glad that somebody is thinking at least :-) Thanks for that.
The voltage drop over a junction in any modern semiconductor is never more then
0.6 V. Specialized switching stuff scores better. But let's assume for the case
that Ducati saved a few pennies. So worst case here is one diode and one 
thyristor
conducting, makes 2 x 0.6 = 1.2 V (The other pair is off)
To get 80 watts you would need .... 80/1,2=67 A ! 
Conclusion:
Nonsense offered with the aura of a proper investigation. 
Misleading heat camera pictures too. The red color is evenly, which is very good
in fact, but there should have been a color to temperature scale. Without that
scale, the "red hot" regulator could in fact be a mere 30 degrees.  Now let's
talk about global warming (but not in this forum) :-)
Regards,

Jos Okhuijsen
