BassPimp66 Posted July 7, 2013 Share Posted July 7, 2013 Oh Grand Wizards of the PCB boards, I have left London a few months back for the US. I'm trying to convert my Markbass MB1000 from 220v to 110v. I understand the trick with the jumpers, and I have located the where it needs to go. The problem is: I don't have any such jumpers and I don't know where to find them. The closest thing I have found is this: http://www.macpalace.com/922-5249-cable-jumper-110v-selector-analog-board.html So expensive!!! and not sure they will fit. Question: where can I get jumpers?????? Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted July 7, 2013 Share Posted July 7, 2013 Are they the same jumpers used in hard drives and PC motherboards? If so try a local computer shop, they cost pennies and will probably give you one for nowt. Also, if you have an old PC lying around, try taking the jumper out of the hard drive and it will probably still work fine depending on the setup - you won't do any damage trying as long as you do it when powered off!

Muzz Posted July 7, 2013 Share Posted July 7, 2013 I did this the other way on an imported LMIII, and IIRC they were standard-sized PC jumpers, so it's definitely worth a try. Quote Link to comment Share on other sites More sharing options...
BassPimp66 Posted July 7, 2013 Author Share Posted July 7, 2013 The jumpers look much bigger than the typical PC hard-drive ones. Quote Link to comment Share on other sites More sharing options...
icastle Posted July 7, 2013 Share Posted July 7, 2013 I personally wouldn't have thought that the standard PC jumpers were actually man enough to run mains voltage through. Quote Link to comment Share on other sites More sharing options...
Muzz Posted July 7, 2013 Share Posted July 7, 2013 I'd be stunned if the voltage ran through them, I'd assume they were a control switch. And I could be wrong about the size, it was a few years ago. Is there not a jumper on there? IIRC (again), I didn't have to add a jumper, I just moved the existing one. Quote Link to comment Share on other sites More sharing options...
BassPimp66 Posted July 8, 2013 Author Share Posted July 8, 2013 FOUND IT !!!! They are called [color=#0000cd]5.08mm pitch connectors / 2-pin[/color]. http://www.ebay.com/itm/300929427722?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 I wish my amp had come with two of these. But, it didn't. $5.5 to this guy in China + a bit of soldering should do the trick. Quote Link to comment Share on other sites More sharing options...

They're really designed to be crimped so be careful not to overdo the solder on them or you'll struggle like hell to get the insert into the housing.

Molex gear looks great though! My soldering iron is smoking in anticipation... [size=4] [/size] [size=4] [/size] Quote Link to comment Share on other sites More sharing options...

[/quote] Not a problem - as long as they make and maintain a good contact with the PCB then it makes no difference in this application.
