    guys, i need some pointers here, im building a rf power amplifier which uses a 2N5913 which can be substituted to 2N4427 but the problem is i cant find those transistors or anything of similar values. any ideas guys?

    oh sorry forgot to mention, i'm from malaysia and sourcing out these parts are a lil tough. i found suitable substitutes but the substitutes are as hard to find as the 2N5913 and 2N4427

    thanx bertus for the input!
    i went around 'shopping' a lil today and i found a transistor 2SC738 but it's for 440Mhz and i was wondering wat'll happen if i use at 145Mhz in my circuit? i mean, like anything bad?
    sorry if it all seems to be a lil 'questiony' im doing all this purely out of hobby and hahahaha have no prior education in this field just know enough to do some basics, sorry again guys :)
