I am not aware of any books that specifically address the difficulties associated with the KundO transistor switched clock.Second said:Thank you for your help. Are there any books out there that might help or web sites?
I sell Brand new circuit boards on e bay to anyone needing new circuit board for electro magnetic clocks. Price is 55.00 plus shippingI am not aware of any books that specifically address the difficulties associated with the KundO transistor switched clock.
The KundO clock and similar were developed by ATO and based on work by Lavet and Hatot; a logical adaptation of the transistor switch applied to the earlier ATO "weak current dry contact switched clocks.
There are books that explain the principle in a few paragraphs but do not address what to do when they quit.
You will find a pleathora of specifics about the KundO and similar on this section of this NAWCC message board using the SEARCH facility. Take a look. Search using the word kundo and specify in Early Electric Clocks an dWatches, 1840 to Present else you will be looking at a whole lot of fixes for 400 day and torsion pendulum clocks made by KundO.
