Sony TC399 - UK Vintage Radio Repair and Restoration Discussion Forum

Hello, my Sony TC399 has started not spooling onto the take up reel, when going into play. It will sometimes work perfectly and play a tape both sides no problem, sometimes it will be playing and the take up reel will suddenly stop and the tape ends up on the floor. The belts are new and everything is clean. I haven't had the hub apart yet, The maintenance diagram suggests a clutch made from felt and lots of thin washers and a circlip. any thoughts? thanks.
I've owned this a good while and its only just started this. Thanks.

Hello It is "Mr Service" time.
The take up spool is driven off the capstan flywheel and if the belt is good then it is down to the slipping clutch thingy.
Have a prod around with the take up see how much torque is there..........you know

Also check the right tape guide for wear or oxide coating.

thanks , yes i looked at the innerds of the reel table and added some sticky backed felt pieces to the large felt ring already in place, this has cured the problem, plenty of torque now had to experiment a fair bit with different thickneses but eventually got it right with other functions rew ff, unimpaired. thanks for youre help.
