It looks like it can be run off 12V DC
http://www.presonus.com/products/BlueTube-DP-v2
Now we’ve improved on the classic unit with the BlueTube DP V2. The solid-state path now feeds PreSonus’ top-of-the-line Class A XMAX™ mic preamplifier with 80 dB of variable gain—an upgrade from the original BlueTube DP’s solid-state stage. The tube path features a 12AX7 tube that operates on voltages double that of other preamplifiers in its class, producing lots of headroom and big tone. We’ve done an assortment of other tweaks as well. The result: Our BlueTube DP V2 offers lower noise, more high-end clarity, and an even smoother tube sound than its predecessor.
2 input channels, each with:
High-headroom Class A XMAX™ mic preamplifier with 80 dB gain range
12AX7 vacuum tube gain stage
Tube Drive tube-saturation control
48V phantom power
80 Hz high-pass filter
-20 dB pad to reduce hot input levels
Polarity-reverse switch
Illuminated analog VU input-level meter
Input/Output
2 balanced combo mic/unbalanced instrument inputs
2 balanced XLR main (L/R) line outputs
2 unbalanced ¼” main (L/R) line outputs
Physical
Compact 1/2U chassis
External 12 VDC, 1A power supply

Dig the analog meters. Saturation control is cool too.
-
I can only imagine the battery consumption running that with my Sony's and the phantom turned on. Still for some reason I want one.
-
BADASS! Classic analog meters and a tube driven saturation control ;D
-
Please excuse my ignorance, I see the electrical consumption stats above, however that doesn't mean much to me.
Could I run this thing for 5 hours on a battery. lithium or sla?

Thanks Jon
Looks like this would work. Not too heavy or big either:

I think the original blue tube was 12 AC not DC .. but that is from a vague memory...

I think you are correct - for awhile it seemed like everybody was in love with AC wall warts...Hope thats over...

I use this battery for my hs-p82 and for the money its the best battery out there. $200 for 153wH battery.
