Hi,

I have finally managed to disassemble the player and measure the ohmic resistance and the voltage.

For a better understanding, I have attached an image where I have numbered the soldering points.



Here is the summary:

Ohmic Resistance, measured with 200k

1 - 2 ~ -140
1 - 3 ~ -70
2 - 3 ~ 6,2 (at 20k)


Voltage measured with V20:

1 - 2 ~ -13
1 - 3 ~ -1
2 - 3 ~ +13

The first number represents the soldering point where I had the red stick on.

I'm not sure if this is enough or even correctly measured. If I can measure more, please let me know. The unit is still disassembled.
