Purchased the manual that I was looking for at a great price and could download it easily.. Great service experience and for future purchases I plan to use the site.
Thank you very much
;
Exactly what was needed to assess the product - excellent value and great service
;
A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.
;
Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
;
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.
5. OCP (OVER CURRENT PROTECTION) CIRCUIT
This circuit is designed to protect the circuit from over current due to overload occurred at the rear of 123[V] line 1) CONFIGURATION OF OCP CIRCUIT
2) EXPLANATION OF THE OPERATION There is very little voltage drop at R423 of 123[V] line. In case that the overload occurs at the rear of 123[V] line, the increase of the voltage drop at R423 bring down the base voltage of the Q407 os as to drive the Q407 Because of the overload at the rear of the R423, the voltage of the point decreases. And this makes Q407 turn on so that a voltage is applied to the #31 of l701. In case that OCP operates by the #31 of the l1701, the set is protected by power off (#42 of l1701 LOW).
