Trouble shooting on a Pioneer SK 757L
Posted 02 January 2011 - 06:00 AM
Now, i open the box, and i found this trouble !! The belt moves sometimes from the motor collar. Why ???
I have a another pioneer box (sk 300) for parts only and i compare the collars. See the photos, it´s grazy
Now, i install the collar from SK300 and the tape running perfectly
It`s a great box with a 30watt power amplifier !!

Lots of features and a heap of controls under that top flap
Cool LEDs too.
I believe it's more like 5w per channel, the power consumption on the rating plate says 30w.

you should do a complete belt change
That flat belt looks really old. I bet that is why it was slipping.

But see the different collars. With the collar from the SK 300 the tape runs perfect. the collar has the same dimension except the additional ring. With this wall, the belt can`t slipping.

Yep. That's why the plastic is shaped like that. I suggest getting new belts and replacing the original 757 collar. It should work perfectly then.
When it's tight, it naturally "climbs" the pulley to the high spot.
