- 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
