This circuit is more stable than previous one. There are 2 set of LC crkts .. to get resonance . 
As the frequency of input signal incteases .. kept on decreasing LC so that resonance should be mailnatined .. Output frequncy is nf where f is input frequency and n is resonance factor .. current value of f is 50khz and nf is 90 khz to 115khz

2 amps through bases is not imba large thing but only if we speak about high voltage power bjt whose have beta sometimes in range of 7 down to even 5 so driving 10amps pulses base flood us with recombination currents at this level. But beta 100 devices in low power circuit hmmmmm only other unquestionable reason of stuffing so high driving current is a vast pleasure u experience doing this. If so there was no question ;))

Secuture This circuit is useful in AM modulation where the actual signal is of low frequency and voltage ,with some external resistances and other components so as to balance current and volatages .
