[Elecraft] no audio output: K1

[Steven J Baumrucker, MD]

I'm in the testing and alignment phase prior to constructing the transmitter
section.  All has checked out perfectly until time to get some noise out for
the 4 band filter board alignment.  I get no audio out at all.

1) sidetone generator puts out sound so U4 must be working
2) all voltages for U3 are correct
3) I can't see any missing components


I suspect I have a component failure somewhere...Q10 or Q11 perhaps?  The
manual states to "trace the audio chain" or something similar and frankly
I'm too dumb to figure this out!

thanks for any help!  I'm getting desperate! :-)

73!
