Hello,
I am going to get the device K8031. On your site there is an instruction on assembly and adjustment. But it is intended only for a case when the device has earned normally. It is sad, but all my designs right after assembly do not work, always there are mistakes. Besides I wish to collect not simply the device, and in details to understand, how it works. Therefore I ask you if it is possible, to send me by e-mail the detailed description of K8031 and the service manual. Oscillograms on pins of a IC13 are especially necessary.
Thank you.
Dest regards, Nick.
Sorry, no descriptions/oscillograms.
If the unit does not work after assembly, and you are unable to troubleshoot it, then you can post your problem here or you can return it for inspection/repair.
