Hey all... just got official confirmation that my KT76's power output is way
low.... classic sign of weak/dying/dead cavity tube. Just looking for suggestions on
what might be a good, cost-effective replacement. I'm tired of futzing with
transponders so I'm pretty sure I want a solid-state replacement.

I just had a thought too (for any avionics techs reading)... perhaps the lack
of DME suppression lead to the premature demise of the KT76? I was going to wire it
up when I installed the DME, but the KT76 doesn't have that capability. Maybe the DME
cooked it?


I would get another KT76. As with all avionics, install price
dominates the end cost.

Alternatively, are there any pin-compatible transponders (for KT76)?



Yes, Narco has a slide in replacement based on their AT165. I've got an
AT165 in my airplane and am very happy with it.
