Can you put extra long line on a 9v transformer?

[TerryD]

I have my power strip on the floor and my Taylor K4 on top of my amp about 6-8 feet away.  I put a long power/plug in line on my transformer to reach the K4.  Could that mess things up?  I get my power transformers from the Salivating Army for a buck and always have the right power,ma and polarity.  Two transformers in a row kind of funked on me.  Coincidence or is there a problem with extended the power line?  Thanks, Terry

You mean you put an extra 8ft 120V extension cord to the 9V wall wart?  Shouldn't cause much of a voltage drop.  Check the AC line voltage at the wall and then  the AC line voltage at the wall wart and see how much voltage drop.  Should be quite minimal.

No, I'm talking about slicing the wire that goes from the transformer and runs to the effect plug in, soldering and keeping the polarity correct.

OK, got it.

Just measure the voltage with the 9V adapter attached to the load, before to extend the wire.  Then just temporarily attach the wire to the 9V adapter and plug it into your pedal load.  If it doesn't drop more than 0.5V and still above 9V, and the transformer is not melting the plastic (i.e. hot), then give it a shot.

I just ran a voltage drop calculator (http://www.stealth316.com/2-wire-resistance.htm).  Although the wire is probably 24awg, the voltage drop over 10ft should be around 0.1V.  Anyways, its easy to try the experiment first.

There is absolutely no reason that it shouldn´t work.Solder the extension cord and put shrinking tubing at all connections.Personally I use one larger shrinking tube over both the + and - connection for more isolation and make it neat.As you say,the last thing to do is to check that the connector is wired right(minus in the hole)which is standard for stompboxes.Take your time to make it neat.Good Luck!
