You are provided by :
i)Three 1nF capacitors and a bypass capacitor
ii) A BJT with hfe= 120 and hre = 3k ohms
iii) Two zener diodes of equal ratings
iv) Assortment of resistors to choose from

Best ResponseYou've already chosen the best response.0fo = (1/sqr(6) (1/(2 PI R C) Volt gain at fo is to be 29 Approximate gain of amplifier is Rc/Re for design input of 10sin((1/sqr(6)RC) The objective is to decrease gain as signal increases until design output, your emitter capacitor may be wrong, should couple input, use zener's somehow to limit gain.
