Hi all

We are trying to help track down where one can purchase the rotary control of the Ecos.
The part is made by soundwell and this is the part :

Problem is they require a minimum of 1000 to order.

We have tried Conrads and Ecos Support do not reply.

All help would be appreciated.

Hi Marius,

there is NO response from ESU !!! Waiting for 2 weeks now.

RS components does not have it .It is preferrable to have the exact one to maintain same solder connections etc.

Found the section in the Ecos2 manual. The fact that this is available may indicate that this is not such an uncommon problem.

WE do not mind getting the whole module just to be safe and the Ecos2 and Ecos1 seem to have the same appearance except for the shape of the joystick and a the little sticker, BUT the board and connection may be different.

I will phone Ecos later today and try and get a direct answer via the hot line number in the Ecos 2 manual.



Thanks

Hi Bert,

Sorry that link is no longer working.

You may not have to replace the potentiometer.

The potentionmeter has a duplicate circuit built in just like the volume control for a stereo. Not sure of the exact technical jargon.

The Ecos only uses one circuit-row of eight pins the other connection ( ie row of eight pins) is directly above.

Only three pins are used and they are directly soldered onto the board.

I simply unsoldered these pins and then soldered three short wires to the same points on the circuit board BUT now to the same pins directly above the original row and it now works perfectly OK.

It is over two years since I did this and to access the potentiometer I remember simply unscrewing the 4 screws directly underneath the controller .
Once these screws are removed the conrol unit will simply lift out - it is connected to the main circuit board via wires and a multi pin plug.

The first time I did this my heart missed a few beats but all is OK with the unit just go slowly.

Good luck and take photos on the way so you can refer back to them.

One other point for future protection my ecos sits in a control box with raised sides so that I cannot accidently put pressure on the protruding part of the knob and I also try to use the left controller more often but being right handed one tends to use the right one.

Hope this helps you out and also other users.

I did the soldering change as described and the knob is better now, although the "speed jumping" has not entirely disappeared. This is not that surprising since that 2nd unused potentiometer contact has done the same amount of movements as the used contacts. Lets hope it lasts for 6 more years now.

BTW looking at the soundwell website, the component looks a lot like this one: http://en.soundwell.cn/n...it_isRefreshParent=false
