The Marco-boy main system, as of August 2020

[karma67]

I'd like to do some rolling. I have Brimar Mill spec 1988 black glass 6SN7s in my copper. I'd like to give something else a go.

As for my croft. I still have the Synvania 6SL7s mill spec in my phono stage as recommended by Marco quite a few years ago now.
