Default Re: Help Pls = Grundig TK64 Motor Not running

WELL ITS FIXED !! YAY

I split the chassis and removed both the 4.3uf and 2uf motor run capacitors.

The new one i had was 5uF and the motor had written on it 6.3uF for 50hz.

So i used my new 5uF in parallel with the old 2uF (which tested ok) to give me a total of 6.6uF. Close enough the required 6.3uF

Put it all back together and it works wonderfully !!

- New bridge rectifier with 1000v 3A diodes, + 100 ohm 10W resistor
- 2x German 50uf+50uF main caps replaced.
- 99% of the wax capacitors replaced
- All new Belts from Germany
- And finally a new 5uF motor run cap (in parallel with the original 2uF)

She SINGS AGAIN !! and will no doubt last longer than me..ha.

Hope all this info helps anyone trying to restore one of these.

Splitting the Chassis is not that hard.. tips
- Remove the Record switch, and push through the hole, no need to disconnect any wires
- Remove the record head two screws and push through the chassis, no need to disconnect the wires
- The pause button and magic, eye assembley, comes out of the way, with 3 screws. Just take the top two screws and one lower down, and disconnect the gear from shaft, and push it out of the way
- Unsolder the motor wires from the tag strip, the motor will lift with the chassis
- move the power amp out of the way, remove the power amp 4 main screws where the heat shied is, and it just moves out of the way. Unplug the main connector, but leave the fat red cable to the input din sockets.
- Remove the 4 large screws holding the chassis togethers
- Remove the 4 screws and metal plate that holds the record switch.

It actually looks worse than it is. With all the above done, you can lift the chassis enough to remove the motor and replace the motor caps. You get about 3-4inches gap, more than enough.

Good luck.
