I ran into the same issue with the motor not delivering any torque on my son's SL-BD22. I found the original repair guide from Technics. In the troubleshooting section they mention several replacement parts. So far I replaced the mentioned elco's and resistors but no juice. Did you ever service any of these where you had to replace electronics parts, like an elco or transistor? Or is it always the motor itself that needs servicing? I'm a bit hesitant to take that one apart like you did.
If torque is an issue, I first suspect the motor. You can remove and de-solder the motor and use a 9v battery connected to the terminals to test. If torque is still an issue, it is more likely the motor/brushes/lube. Just be very careful taking it apart so you don't break a contact off of one of the brushes.
@@millervintagehifi3034 Well, turns out you were lucky the way the motor came apart. In my case, the central axle remained stuck to the copper spindle and was pulled free from the motor core. After that it was impossible to put it back together without breaking things.
Hey! Great video, thanks for the valuable information! I have the same model but does not start rotating once i pull the needle towards the plate, unless i give the place a simple push (and then it starts normally). Any thoughts?
Take the platter and belt off and see how much torque is present on the motor spindle when you move the arm over. If you can easily stop the motor from spinning, then the motor needs to be serviced - there is carbon build-up on the brushes and/or the bearings need to be lubed.
@@millervintagehifi3034 Thank you so so much for the quick reply! One more question (maybe related?) After the turntable plays for, let's say, one side of a typical LP, it then starts and vary the speed of the turns (mostly drops speed rate). Any thoughts on that!? [Haven't verified yet, but i think that if i put it on que and then play again it regains it's speed (need to test more to be certain?)]
It would be much more cost effective to purchase a working table off of eBay or locally. The risk in shipping a table back/forth is expensive, as would be the repair depending on what the issue might be.
