Default Re: Help with Braun MT99R

MT99R is a USA export model. It is a late valve model, I'm surprised that it is not transistors.

The voltage of the motor on the record deck you have will determine if and where it can be connected for power to the turntable.

The black DIN socket in the centre is likely to be a tape in/out connection not pickup.
The EL84 valve is not in its socket fully.
This valve will most likely need its grid coupling capacitor - C69 on the diagram - replacing before you use the chassis if you are to avoid destroying the irreplaceable output transformer &/or valve.

Does the instruction leaflet not show the socket locations? If not you may have to follow the wires from the selector switch in the gram position.

Do you have a circuit diagram you could post?

I've found you the circuit diagram,

the pickup is in the dotted box at the bottom. It would seem that the motor was a mains one and was connected directly to the mains.
