Hi

I am replacing caps on the modulator board. But I am a little unsure on some caps...

I have a diagram of the board in the servicemanual, but it does not match mine exactly.

I know for other parts there 2 diagram for up til sn. 260028 and after…..but only one cd4 diagram....my bg is slightly above 260028.

Does anyone have another diagram than the one in the servicemanual?

One existing tantal is mounted reverse polarity of both markings on the board and the diagram I have.
Should I mount it as it is? Any advice?

Torben

I can’t help you on the version of the diagram; however, the circuit will dictate the polarity of the cap regardless of the markings. Which cap are you referring to?
