hi, sorry if this has been solved/posted etc before i suffer from ads which is a great excuse for a short attention span, in other words i haven't searched past posts, alias lazy bugger. i have a standard 600 ohm output signal generator and want to experiment with frequency, wave forms, amplitude etc on home made/wound ferrite transformers. if i feed my sig gen into a emitter follower (high imp in, low out) as per the cct attached, and "ground" my negative sig gen output to the negative rail of the cct should that be ok? r2 and r3 10k for near unity gain and r2 a bit higher for some usable gain? as i'm messing with 25khz + c1 could be 1uf? i'm obviously "green" on all this so any help greatly appreciated, and i apologise for any stupid questions in advance, thanks.
