Replacement for the 2SC1971 Transistor

[Jmsheehan86]

Hello, I tried to build this circuit in the link below with some 2SC1971 RF Transistors I received from Ebay. Needless to say I learned that they were counterfeit and that getting the actual genuine 2SC1971 Transistor is actually hard to come by so I looked up an equivalent transistor. As I read on some sites the NTE342 is a good replacement and will work in the spot but before I go and get the transistor I wanted to know if it will work in this amplifier or should the amplifier be redesigned.

Or what other transistors could I use.
MRF260?
NTE235?
