General passive-line level filtering issues. (BD-Design)

Hallo Bert!

You are right of course - my concept needs a low impedance preamp. Neither a valve- amp nor a TVC has a low enough impedance.
Some years ago I build a valve-amp, which could drive a 75 ohms load, but it was a lot of expensive parts used...
Best regards
Stephan
