Hi, I'm new to this and trying to bring a Kenwood KR-9400 back to life. (Progress thread).
I have a nice scope (Tek 465), a function generator, an adjustable bench power supply, a couple of multimeters, and a dummy load.
Here's my question… It seems to me that it should be possible to run a signal into a board (like the amp board under test in the aforementioned thread), then, using the schematic and scope, trace the signal through the circuit to identify problem components. Right or wrong?
It seems that this would be a faster and easier method than having to desolder diode leads and pull transistors, etc. and meter them individually.
Any knowledgeable techs want to set me straight? Links to tutorials on using a signal & scope to find faults would be fantastic (believe me, I've looked - my electronics bookmarks have grown exponentially, but I'm not getting much relevance).
Thanks in advance.
