Oh really? Wow.. the highest I could find up here was 1amp... maybe they put out a new line since.. I should take a look. Do those adapters have built in fuses?

I always just use the internal batteries to turn it on.

Yeah, I guess during regular recording, the JB3 won't pull more than 1amp... I used a 1amp adapter a while back for a few shows and it seemed to work fine. I was just paranoid so I got that walmart 2amp adapter but it shit the bed on me a few months back. I'm looking into that VR box that is being discussed now... still gotta find a walmart lion battery though.... it's hard to find all this shit up in canada.

This box looks very tasty.  But it would mean order 4 pins, and I love getting everything local.  Lee is my hero

4 pins just means you can use the same cables as you would with SLA or other pro-style powering systems.

+T to lee for keeping things standard (instead of creating ANOTHER uniquely pinned cable to sort out)...

i think this will be handy in my bag at any show

my 2 internals work for most anything i tape, untill the summertime for festies.

im having a custom cable made out of 2 wally l-ion pack cords to wire 2 l-ion packs together to get 9v 10.8AH > 5v and 6v outputs

wonder if he could make one with 3 putputs? 1 5v for my jb3 and 2 6v outputs. that extra 6v output would save the day for some taper eventually, and would make running an extra piece of gear much easier (like the mini-mp i borrow from time to time :) )... hmmm

im pretty sure he can dustin, we discussed this awhile back

originally, he wanted it to have a 7.2-35v input> 5v
                                                                > 6v
                                                        and input=output

so if youre running 7.2v in, then youd have a 7.2v out also

Until now :)

thanks for the clarification -- if Jason confirms that the 12 v adaptor will also work with a 9v lithium ion batt, I'm golden :)

Sorry to have spaced on ya.

It starts up fine on the walmart 9v. I scrolled menus and played back a.o.k.

I'll do a record time test over the weekend.

yup. i can add additional outputs as long as the total current draw doesn't exceed the LM317's specs (1.5A). 

in dustin's case, he wants another 6v output to power a preamp. rather than spliting the output of the 6v VR circuit to 2, i'll simply add another 6v VR circuit so each 6v output can handle 1.5A of current draw, rather than 1.5A total.

i'll simply need to get a slightly larger Hammond box to accomodate the 3 XLR panel mounts
