Go to the Elecraft mail archives and search for the thread "K3 speaker amp - sub side inop."
It's a tricky part to replace, but it's $5 if you do it yourself, vs. about $140 (shipping, parts, labor) if Elecraft does it. Another option is to just leave it dead, which I think I will do next time it blows up. I don't know why it is so delicate. A good rule is never turn off the agc with speaker connected.
