Hi, thanks for the informative posting of the repair blog.
I'm hoping you might be able to give me a few tips.
I have a KSW-15 that started giving distorted output. At first I thought it might be a torn speaker cone but the cone looks good.
Next I thought it might have a bipolar power supply that had a bad positive or negative supply. Unfortunately without an electrical schematic it is tough to trace. Is a schemtic available for these units?
IN terms of experience, I have a BSEE and experience working on solid sate and tube amps for bands as well as consumer TVs, stereo amps, dvd players, etc.
Thanks in advance, Mike D.
