Topic: affordable JB3 power supply options???

[mikesalvo]

anyone? Ive never looked into this, and with festival season coming, Im gonna need something that can make my deck roll for longer than 2 sets...

Digital Concepts PP99

This powers my JB3 for a 3 hour show, easily.

i bought one of these and my jb3 froze up the only two times i used it 

i know a lot of people have used these without any problems, i just recommend testing the battery before you use it in the field

i'll find a link to the new power supply i bought for my jb3.  it was $60 but it is sweet.

[twatts (pants are so over-rated...)]

I used a 12v SLA spliced into the 12v Car Charger...

+t all around guys. Im def. looking for more than 3 hrs. time. FanOf TheMule Id love to know what your $60 solution is and how long you get. Also, the 12v SLA, how long do you get out of it? will it be able to power the JB3 right out of the box???

How about killing 2 birds with one stone? I know you were looking for something to power the AD20 as well a little bit ago. If the AD20 takes a 9V DC then you should be looking for someone to make you a "Juicebox." I think Nick's Picks posted that he is able to make them, I may be wrong though. Todd R. of Segue Enterprises (no longer making these) made me a Juicebox to power both my UA-5 (9V) and my JB3 (5V) from a single 9V lion battery. It will run both devices for around 5 hours. It has a 7-14V Input, a Pass-thru Output, and also a 5V DC Output.

I used to run the same rig you've got ( PS-2 > AD-20 > JB3) and powered it all with 9.6 volt RC batteries - something along the lines of these - http://www.batteryspace.com/index.asp?PageAction=VIEWCATS&Category=273.

Powering the PS-2 and AD-20 from these batteries is trivial as they can be powered by the 9.6 volt batteries directly.  Powering the JB3 is a little trickier but still quite easy.  You'll need a voltage adapter.  You can use an adapter made to run off of 12volts since these batteries are still more than the 5 volts the adapter is putting out.  Creative makes car adapters that work well.  You can also buy one from Radio Shack that is switchable and works when set to put out 4.5 volts.  You'll want an adaptaplug B on it, tip (+) ring (-).

If you've got basic soldering skills rigging up something that will connect the battery to a couple of 1/8" plugs for the AD-20 and PS-2 as well as the voltage adapter and a plug for the JB3 is pretty easy.  If you don't feel comfortable with a soldering iron I can make one up for you but I won't be able to get to it for a couple of weeks.

There's lots of good info on powering a JB3 in the Nomad JB3 Tapers FAQ - http://taperssection.com/index.php/topic,16338.0.html

I just realized that I made you a cable to power the AD-20 and PS-2 from 9.6 volt batteries a while ago.  Send me back that cable and I'll add a segment to it to power your JB3 too.  The parts for a voltage regulator shouldn't cost much.  If you're interested, let me know and I'll figure out what it will cost.

the trick with the PP 99 is too use it between sets.  the external can make the jb3 freeze up. (hasnt happened to me but PBum and Trego have told me about it)  so i only use mine between sets for charging purposes.  it add hours to my jb3 battery life. (given that the setbreak is longer than 15 minutes)  Considering the PP 99 is only $20 i think its a good deal...

[kskreider]

I guess that I should have mentioned that I do have one internal battery as well as the PP99.  I have been using the PP99 regularly for at least two years and have NEVER had a lock up and I use it for power and not to recharge between sets as chrisdavis mentions.  That sounds pretty foolproof though.

Good tips here....just logged on to look for an external solution for the JB3. The two internal batteries I have are over 3yrs old with hundred and hundreds of hours on them...they just don't seem to hold a charge as long these days, about 3 hours or so, only.

Been using the 9.6V RC car batteries for two years now with the AD20 and PS2. Has worked flawlessly. Learned how to solder on this project too

So....I think I'm headed out to rat shack right now to get the volt adapter, B plug and a new batt.

Will report back upon completion. Thanks folks!

rdfager PM sent....

[tbrown4]

Ok....so....Rat shack folks looked at me like I have six heads when I asked for a volt reg. Ughh. Any links online where I could get what I need?

[mikesalvo]

strange. usually their good on all topics there (although a lil' pricey for alot of things IMHO)
