Topic: JB3 plug size/power

[bagtagsell]

I use to have a JB3 and ran this to power it:
10 amp SLA>alligator clips female cigarette lighter thing (radio shack)>Universal Car power kit (with selectable voltage or the creative one)>NJB3. 

My question is what letter from radio shack coresponds to the right power jack.  (At radio shack they assign a letter to correspond to the universal input jacks)

Also using the above system which do I turn the voltage dial to?  3v, 4.5v, 6v, 9v, 12v...
The information is probably out there already I just didn't find it

From the FAQ:

[155] What size DC external power plug does the JB3 use?

Outer Diameter:  4.0mm / Inner Diameter:  1.7mm
Radio Shack Adaptaplug B

Well, not until just now when I updated it, anyway.
