** The vast majority of SS phono preamps fitted to amps and receivers are
hum free and have very low noise - your unit is either faulty or bady set
up.

Building a phono preamp with tubes that can match a SS one for absence of
noise and hum NOT a trivial task.

Phil is right, even my Techniks is quieter then the "custom phono pre amp" I last built, and I was proud of it having
-70db!

You should also check into problems with your record player or it's pickup. If that's the problem, a new pre amp won't
solve anything.

And really, if you have to ask how to build it, you aren't going to beat the manufacturers at their game...
