None that I know of, but I don't know the tube complement of the 5/10  
kW "Amplifuzz".

The RCA high-level designs below 50 kW generally had identical tubes  
in the modulator and in the Class C RF final, and the 10 kW designs  
had two tubes, whereas the 5 kW designs had one tube.

5 kW units with 10 kW modulators were known.

Sure, some of those went to stations on Regional channels (as Class  
IIIs), but some went to stations on Clear channels (as Class II-Bs)  
and which, theoretically, could have been upgraded to 10 kW at a  
later date after an associated array change.

One station I am aware of was designed at the outset with 10 kW and  
50 kW in mind, but was built as 5 kW, where it remains to this day,  
the owner-operator (and designer) having become a silent key.

For years, decades, really, it used a 5 kW RCA which was built as a  
10 kW in anticipation of the upgrade which never came about.
