How would you power the Original Art Tube MP?

Not trying to be stealthy, just need something to last a few days.

[hi and lo]

I recommend an AC outlet and adapter! 

[Lil Kim Jong-Il]

I'd use a 12-14V battery like the ones we use for a 722 and a small power inverter to drive the wall wart.  That preamp doesn't draw much power but the inverter is going to be inefficient so you should check the current requirement of the inverter under load against the max current the battery wants to source to ensure that you don't hose the battery. 

Something like this http://www.amazon.com/Duracell-813-0281-07-Pocket-Power-Inverter/dp/B000U0M7OW/ref=sr_1_13 would easily fit into your taping bag with a couple of LIon batteries.

Thank you lil kim, but i'm looking more for something to use to power it while recording.

I think he meant you chop off the cigarette adapter and wire it to your batteries

hahaha fuck yeah, thanks

I'd have to use a regulator for that though would I?

I've seen a taper in Raleigh use something similar to this:  http://www.sears.com/shc/s/p_10153_12605_02871988000P?blockNo=1&blockType=L1&prdNo=1&i_cntr=1302635535385

Its got 12vDC as well as 120vAC...

You'll need to power TWO of those if you plan on running in stereo as that is a mono pre...

No.  The inverter accepts 14V-10V input and produces 120VAC.  Your preamp power supply plug into the inverter to produce the 9VAC the preamp wants.

You can cut the wire between the cigarette plug and the inverter and insert a molex or 4-pin XLR connector so that you can put it back together for road trips and then make a little harness for connecting the inverter to your portable batteries.  My preference would be the 4 pin XLR wired to the usual standard: pin 4 for hot (+12v) and pin 1 for ground.

Of course another option is a female cigarette adapter to wire to your batteries like this http://www.powerwerx.com/adapter-extension-cables/cigarette-lighter-socket-fused-powerpole.html.  The link is just for example.  I know you can get one for a lot less than that.

Thanks for the advice everyone, founds what I'm looking for.

The output of most inverters is DIRTY.   Most a/c devices depend on the oh-so-clean power that comes from the electric company.  Pure sine wave inverters are expensive.

Whats all this add up to? fairly new to the terminology

I wouldn't say that most devices require clean AC.  Most of the problem is for devices like A/V gear where a cheap power supply will leak noise into the signal intended for display/recording.  It's certainly no problem for battery charging or running a PC or similar load. 

I don't have access to a scope right now but maybe someone on here could take a look.  That would be an interesting wave capture to see.

I actually ran one of these for some phish shows in 98. I used a small battery and inverter. Worked good, no noise from the inverter. Don't push the tube too hard or it will distort.
