I want to adjust the time back to winter time and guess what? The adjuster breaks off



Tried to reglue it


Then I tried to make two clock one by using the w116 print and the w123 mechanism.



Left one is W116 300sd and right one w123 300d
Both has the same resistor on the tester.







tried to replace all the components but, doesn't work.



This one works:



Comparison of the chip blanks



120ohm on the main resistor 118.9 is <5% is pass.



Then I greased everything so that it won't rust





Back to one piece



I replaced the caps before already.



Then I tried to hook up the tachometer to see if it works:



Fan 1500rpm > tachometer 1500rpm
