RE: question on PSUs

I don't have the technical chops to do it myself--at least without some help--but I am interested in powering a computer with SLAs.

I am using Red Wine Audio S-70.2 SLA powered amps, and this seems to me the way to go. Red Wine is coming with a battery-powered DAC/tube preamp this spring, which I will certainly try. That will leave only my computer running on AC.

Check out the Red Wine forum

The advantages are that battery power is free of ac-line grunge and the inherent 60 cycle hum; it is free of the noise that is produced in rectifying and filtering AC; and SLAs allow very powerful current surges that get choked out by AC power supplies. This seems what the doctor order for an audio PC.

The S-70.2s each have two 12 volt SLAs. The amps put out 30 watts, and they will run 20 hours or more on a charge. The forthcoming preamp/dac is supposed to run 6-8 hours on a charge, keeping the filaments of two vacuum tubes hot.

I am satisfied customer of Red Wine Audio, but have no other connection.
