First the background...
	
	What I am planning to do is build an amp with trebble, bass, balance 
and volume controls that fits in a 3.5 bay and has connecting leads to 
speaker ports at the rear of the computer. The input will be from a 
sound blaster card that give 4 watt and plan to run this through the 
lm1875 (I think) to get 20 watt. To run this chip, I shall raise the disks 
bays 12 V to 30 V using a dc/dc converter.

Now the question...
	
	Now, I know that the drive lines have both 12 and 5 volt supplies 
and respective grounds for each but,	
	Can anyone tell me what sort of maximum current you can expect to 
get out of the supply line for floppy drives?
Any recommendations or comments welcomed.
Thanks
