I have this Kenwood stereo receiver model VR-306 and the unit shuts down a few seconds after power switched pressed. It will run with output module STK410-030 removed from the circuit, or it will run with the STK installed but the wide ribbon cable from the main board to the front panel disconnected. I have tried a new STK but that didn't solve the problem. I am now attempting to trace the protect circuit but don't have a schematic or pinout of the STK410-030. I checked Google, B&D, and Tech Assist members page. There is a manual for a different Kenwood there but it uses a differnet module with less number of pins. So far the only voltages I have detected that don't seem right is across R361 or R362. One of them has a voltage (26V if I remember corectly) and the other resistor doesn't have a voltage across it. Both these resistors appear to go to the output module, probably one resistor for one channel, the other resitor for the other channel. Thanks for any help. -- Gary McCartney McCartney Electronics Guelph Ontario Canada Est. 1984 email: gary (at) number63.ca ***************************************************************************** Classifieds!
