Hi,
I have an Ibasso D1. It has been my mainstay USB dac for some time and been using it as a pre-amp for my Alesis Monitors. I have not come across another amp that sounds as clean and warm.
Unfortunately one of the channels has failed on the AUX analogue in. I think it is the input connector rather than anything in the signal path.
My plan is to dismantle the D1, fabricate a new mini desktop case and make a few upgrades/additions Including:
>Change the Push button power to a flick switch (remove power on pop/click)
>Change the 3.5mm Input output for gold RCA terminals (this will hopefuly fix the lost right channel too)
>Add an input selector switch and wire this into the Analogue input circuit.
All of this is fairly rudimentary, however to be done properly I will need to desolder the existing terminals. I have some wick, and am intermediate at soldering in general, but have little experience desoldering PCB. I want to be sure I do not damage any components.
I have considered a less elegant solution, of just leaving the terminals in place, and soldering hookup wire direct from the solder points on the underside of the board.
So.. My questions:
>Does anyone have or know of a circuit diagram for the Ibasso D1?
>Does anyone know the type of solder used on the board (leaded, lead free.. silver solder..)
>If I use lead free, and its leaded already on the PCB, could this cause issues?
>Is there any advice, general things to be careful of when trying to desolder?
>What is a good input selector pot. I want to ensure there is no 'click' or 'pop' added in the signal path. I also want to ensure I don't add any noise or distortion..
Lastly, if anyone knows of somewhere that can fabricate aluminium face and back plates to specification that would be great.
thanks a lot everyone.
