If I do end up having to get a new transponder,

to cost more than the GTX327 ?

The KT76C is a drop in replacement that could be
why.

The KT-76C is also still a cavity-tube type of transponder, and will
be subject to the tube-related problems just like the rest of the
older technology transponders, despite the fact that it's got a nice
digital display and interface.

That's why we opted to bite the bullet and pay for a new GTX-320A plus
installation instead when the old King transponder bit the dust only a
few months after buying the 172. Wish now that we'd have paid the
extra
~ $500 and got the pushbutton GTX-327 instead.
