Hmmm sorry for being a total noob when it comes to electronics, but can I charge the 9V battery without taking it out of the 2stepdance?

Hi iRoux,
 
The battery has to be removed to recharge it.  
 
Plugging a power supply into the jack at the rear of the Stepdance or 2Stepdance bypasses the internal battery - unless the external supply voltage drops below the voltage of the internal battery, and then the Stepdance smartly switches back to the internal battery.

Hey everyone,
 
Some of you may remember me from the earlier pages in the thread.  I have been relatively silent about the amp as of late due to my failed attempt at replacing the unit's voltage converter, thus I haven't been able to use the unit in high voltage/current mode nor with an external adapter for several months now, and I just wanted to give some kudos to Jan Meier for offering to help me replace the chip.  He is one of the rare gentlemen in the audio business, and my only regret is not having sent the amp off a year ago to be fixed.  I think Jan deserves a lot of thanks for not only designing a great series of headphone amps, but also for backing his product with exemplary customer service.  I think my favorite headphones with the Stepdance are the Sennheiser HD598, as the amp is able to give the HD598 a degree of clarity and bass tightness not found with conventional headphone amp designs in my experience.  I will be going through major Stepdance withdrawal for the next few weeks as I send off the amp in a couple of days to Germany, but I know it will be worth it in the long run to be able to fully experience the full sound quality of the amp for the first time in a year.

To dim the LED

Brilliant!  
 
(Or I should say, "Less Brilliant!")
 
Seriously - that's a mod I'd like to try.

Jeah..just try it

I'd like to try it, but I'm chicken!   BAWK-bawk-bawk-bawk-bawk!   

 
Maybe I'll just paint the LED with several coats of translucent blue lacquer until it's sufficiently dimmed!  

 
(But the heat might craze the lacquer...)

This is also possible and much more easier

 

[zilch0md]

 
But nowhere near as sweet as your solution.  Seriously - my hats's off to you for adding a rheostat - you can set it to any brightness you want. Cool!

Actually I wanted to dim it because it was too shiny in the night but I have to test it today if there are any great changes. If not I have to change the potentiometer by another one with more resistance. Right now I am using a 10k poti and a 1k series resistor. Originally are 4K7 Ohm used.

Well, I'm happy for you because I've often thought that the LED was too bright - especially for night time use, as you've pointed out.
 
Enjoy the fruits of your skill and labor!
 

 

[monoethylene]

I ve changed the series resistance to 9K Ohm and now it is really to dim

Any one know where I can get the AC plug. I have a 15 v regulated power supply. The 3.5mm outside diameter plug I had/tried dosent work.

I suspect you meant to ask where you could get the DC plug.
 
Get a Type H Coaxial Connector from Radio Shack:
