Default Line stage

I would like a nice cheep (say under $300 US) line stage to be able to drive a 400 ohm load at 30v +- any ideas.

Thanks,

Woody Dlaz441@aol.com

Default Low output impeadence Preamp

You might want to look at the cheapskates preamp
http://home.t-online.de/home/MHuber/pre-5687.htm

or a design that uses one of my favorite tubes 6C45

or maybe a 6H30

Thanks for the feedback. I might try something like that but with a load resistor instead of the current tube current sorse.

Just remember Woody, that low output Z and the ability to drive a low Z load are not the same thing.

Good one, Brett.

Also, Woody, unless you welcome tons of spam mail...camouflage any e-mail address you publicise.

Cheers,
