Some time ago I managed to get hold of a DCC 900. The previous owner mentioned that it had undergone some maintenance, but that the player suddenly stopped working afterwards.
I’ve now taken both boards out of the unit and I’m seeing quite a few corroded components. Would this be considered beyond repair, or could it potentially be resolved with something like an ultrasonic cleaning bath?
Also, the way the repair work has been done doesn’t look particularly neat to me. What’s your opinion on this, and do you have any suggestions for a possible solution.
Hi Ralf. Thank you for your answer. I know that the boards can be bought via the DCC shop but i like to keep the system as original as possible so if i want to take the effort to clean it or solve it another way, what is the best option to maybe solve the issue? Ps. Are both boards available if it is not possible to solve?
That board is just asking for 8V to be send straight to the head and then it is game over for the head.
The reason the new board was developed is because there were so many problems. Even if you get it to work, it still might fail later. The acid damage never stops eating copper.
Last week I had to restore one done 3 years ago by someone else.
Worked fine until it did not. It still damaged the head.
What we do at the museum, is keep the board with the player, but put a new board in anyway. We do have donor audio boards and hope in the future to be building new ones as well.
