Hi guys, great forum.I've just bought a couple of "Smartkit 1028" transmitter kits.I've assembled both and they're working fine apart from some poor audio issues.One uses a 2n3553 and gives out almost almost 3 watts, the other uses a 2sc1947 and boots out just over 4 watts.I think i've found a mistake on the supplied schematic in the preamp stage but want some assistance to confirm it(see if you can spot it).Anyway, on this note - the audio is either quiet or very distorted while being fed from a personal cd player in mono regardless of spending ages playing about with vr1 and varying the audio from the cd player.Please have a look at this link 4 Watt FM Transmitter ..I hope i'm allowed to post this link by the way.I'm ripping my hair out here, please help me and see if you can see the mistake in the preamp stage.If it is a mistake that is.Cheers in advance guys.
