tube PA reccomandation?

[Gabi]

Alrait.

I know some of you already built this one.

But I am looking for a regular schematic, to build a stereo budget PA system on tubes.
I know, budget-tubes don't go together, but I know there are some schematic worth take a look at.

It will be intended to be used mainly as a practice PA system. Let's say maybe with an added tube-based mic preamp.

I am thinking of 50-100W os somewhere there...

thanks,
gabi.
