Hey guys,Got me a beocenter 7700

Now here’s the thing, it was dead.

Started rebuilding the amp board, the cassetteplayer, and a few cosmetic things like the lids lamps etc.

Got it going again and it sounds great!

But......the record player is not responding on the 33 and 45 rpm switch when pressed.

It will play a record when pressing PH from beginning to end.

Could anyone give me a shortcut on where to get this problem solved?

Thanks in advance, any input will be much appreciated.

Steve
