KAT100 Finished but not working

[Doug Person-4]

I've had a KAT100 sitting under my workbench for several years. I sorta
forgot about it. A couple of days ago I recognized the box, pulled it
out and assembled it. I've built dozens of K-Kits. This is the third
KAT100 I've built. I'm very careful. But... This one doesn't want to work.

There is no indication that it is active - LEDs don't light. I carefully
examine every connection under a magnifying glass. Transistors, diodes
and ICs are all correct. Every connection looks perfect. I traced power
to every IC - everything is correct. I even carefully built a new
control cable - just to be sure.

Can anyone suggest what further steps I can take to debug this tuner?
Could there be something wrong with the K2? Any help appreciated.


Thanks -- Doug -- K0DXV
