Hi folks. After months of trouble shooting we have finally fixed the total recall in my console.
Some crude information, the recall card that is under the G Keyboard had quite a bit wrong. There were 4 failed 10ohm resistors, 1 blown fairchild transistor 1 failed opto isolator. Here is a pic of the console undergoing surgery.
Next week I will upload the circuit diagram with markings of what was fixed.
The board is the one sitting on top of the white padded envelope.
I still have 16 channels that are playing up, it is my opinion that the multiplexers in these channels need replacing, I will report once I've done this.
Stef.
