	I've got one comment on power-amps when rolling-your-own.
	In the power supply, the bigger the caps you use the better
	the ripple filtering (60Hz stuff) BUT ALSO the bigger the
	current surge through your rectifying diodes.
	
	As the ripple gets smaller the 'conducting-time' (forward bias)
	of the rectifying diodes gets smaller. If the power to the 
	load stays the same then the current during foward bias gets bigger.
	(lots bigger, the average current [over time] must be constant 
	for a given load.)
	
	So, for mongo(big) use mongo rectifiers.
	
	just a thought. :)
