Hello to all,
Please be patient. My background is in mechanical engineering but I am a novice when it comes to turntables.
I am trying to repair my friends Dual 1264 turntable. This unit has not been played for about 20 years. During a preliminary look over I discovered the following problems.
01. 33 1/3 records will not drop when stacked on the AW 3 changing spindle. I cleaned the spindle thoroughly. I can not figure out the mechanism that activates the lower three pawls. The upper pawls work when I manually depress the lower shaft of the spindle.
02. The release rocker arm (AW) was frozen from non use.
03. The changer actuator rod, which is activated by the release rocker arm (AW) had limited movement due to lack of lubricant.
04. The pitch control belt (109) is broke.
05. The tone arm will not do it's thing. It just raises up and down the then
the machine shuts off. This probably occurred during improper transit.
The difficultly with this unit is the quantity and complexity of the linkages. In my opinion, the service manual leaves a little to be disired and is directed toward trained technicians. But if anyone has any suggestions, as to what my next step should be, your efforts will be greatly appreciated. Ted
