Hi, I am a newbie. I am interested in getting a Line-stage tube preamp for
teaming up with my SS amp. The Line-stage tube preamp offer 2 version
of power supply- one is SS the other is tube . I wonder would there be
any sonic advantages of tubed- over the SS power supply ? Your
explaination and opinion is highly appreciated and thanks in advance
Simon

Exactly which products are you investigating? I can find several products
that fit your general description.

Depends on the implementation, which is why I'm asking for more specifics. .
I can see some advantage of DC power for the tube filaments, which
practically presupposes a power supply that it is at least partially solid
state.

Thanks Mr.Krueger. I am investigating the Tubed and the SS Power supply
namely: the PSIt and the PS1 by Mapletree Audio Design, here is the link
http://hollowstate.netfirms.com/

I am interested in either the PSIt or PS1 for the Line2A tube preamp application.
Your opion and suggestions is highly appreciated and thanks in advance

I have to admit that my CJ tubed preamp has a SS power supply. But, I like
the idea of a slow application of B+. It's too bad they didn't put a time
delay in their SS power supply. The tubed power supply does use SS rectifier
and regulator for the filament supply, which is a big advantage.

Thanks again,Mr.Krueger. Do you think the PSIt would work better than
the PS1 (on the Line2A preamp application)?

Waiting for the filament to heat up enough to start boiling electrons
off the cathode to be attracted to the plate sort of counts as a slow
application of B+, doesn't it?

More than sorta. It just does! I find it hard to believe that there aren't
more SS power supplies for tubed equipment that have a time delay on the B+.
Some of these devices even have separate transformers for the B+ which means
that a SCR on the primary side could provide the required control function.

If you've got B+ on the plate but no heater current, can the tube suffer harm?

Cathode stripping is completely misunderstood and misstated in that article.
A reference where the effect is at least understood and sorta well explained
