Sc The real problem is that the pre-amps don't accomplish anything. They are just a gimmick since they are unable to improve the signal-to-noise ratio. All they do is boost everything... noise and all... LOL www.telstar-electronics.com This is actually not correct. A good pre-amp would have bit better s/n ratio then the set it is used with. I have experiemented a lot in the long ago past with different configurations for pre-amps, like transistor, MOSFET, FET, cascode etc... Best I could come up with was 2 junction FETS in cascode..... Maybe these days there are better solutions. But I received the world on a little wire with SSB. So, your next project: A good low S/N ratio pre-amp? Probably not. Maybe you were using your power amp as pre-amp? |
