Hello Hank,
I had the same issue with an Eastern Electric integrated vacuum tube
amplifier and my computer.
I guess it's the way the power supply in my computer and the amplifier are
grounded.
I couldn't do this with the computer, so I done it with the amp.
I lifted the ground wire from the chassis to get red of that humming
noise.
When you have an amplifier that uses a pare of 5AR4 tubes or any kind of a
tube for a rectifier, you'll run in to that problem, especially if the
power cord is earth grounded.
Let the truth be told, that earth ground wire is not needed.
The thing can work without it.
But don't do this unless you really know what you're doing.
Because if you don't, you can get 1 nasty electric shock!
Hope this helps.
My best regards.
John.

High Garry,
Those phono preamps are for computer use, you'd have to have some kind
of an adapter in order to put that in to a line in.
You would need a phono preamp for hi phi use.
Hope this clarifies it.
My best regards.
John.

go to the tracertech site and you will find a couple of inexpensive
phono preamps. a valve is what the British used to call vacuum tubes. a
valve EQ would be huge.

Hello Tom and Hank,
Finding a mixer with phono inputs these days, is just like looking
for a sonic needle in a sonic hay stack.
Your best bet, is to buy a phono preamp from a hi phi stereo store
and plug it in to 1 of the sets of line ins on the mixer.
Hope this helps.
My best regards.
John.
