[Elecraft] Still need help with K6XX CW Tuning Indicator on K1

[George Averill]

All,

I feel like I’m trying to perform brain surgery with a pocket knife.  All of my test equipment is as ancient as I am. HI  Where did all the tubes go?

The first kit didn’t work so I have ordered another one.  That should solve the problem if the problem is the IC in the kit.  I will also try to take more time soldering the surface mount components this time.

What really puzzles me is that, with the kit out of the circuit, and using a scope, I have never been able to pull a 600 Hz  sidetone signal off the side of the volume control, but I can off the speaker.  I’m positive that the wire to the volume control is OK, and it’s connected to AF1 at the volume control coming from the AF Preamp.  It’s also connected as per the instructions that came with the kit.

Any help or suggestions would be appreciated.
