Thanks for starting this thread.  I have always wondered what having more than two tubes in a line stage accomplishes but never got around to asking.

When I mention two tubes, I am assuming the preamp does not use a tube rectifier.

McIntosh C220, with remote, with phono, total 4 tubes

’cool tube glow' out the top seems to be it’s claim to fame
