[Amps] Tuned Input for G-G 50Mhz amp

[TL_IARC]

Hi Carl,
Thanks.
I thought a "Tee" would be easy to tune outside the amp in real time (one 
cap), and would basically achieve the same result as the "Pi".
Someone elsewhere mentioned better harmonic treatment with the Pi, but I 
can't relate to that as I have limited knowledge.
