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 option and suggestions is highly appreciated and
thanks in advance Simon

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.

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?
