True, but if you look at the tank circuit running a pair isn't is about 
the same as Palstar uses.
Alpha uses a 4CX1500B for the legal limit out with a conventional pin 
net, or Pi-L.
There are a number of 2-meter amps including the 2002A that *suggest* 
stubs or a network on the output.
It appears the Palstar 2-meter amp uses a pair of tubes in the same type 
of circuit the 2002A uses although they use the Russian Tetrode 
(4CX-800) instead of the 3CX800.

I don't see anything in the circuit compared to other legal limit 
6-meter amps that would keep it from certification unless it'd be the 
tubes themselves.
