I have been asked about using a tube amp with

Well, you might not find a transformer with precisely the PPP primary
ratio to match whatever you would have used for PP. Some of us might
even sacrifice some of the greater power to up the primary to plate
multiple for greater silence.

Indeed:-)
I have built some PPP amps before, and the primary Z was
half that of the PP version.

I have a Velleman K4000 PPP amp which
was built for the power, and it is just as well that it has 18W in
Class A, because it is a Jekyll and Hyde affair, very sweet until you
attach (very) insensitive speakers and turn up the wick on a 100W of
PPP power, when it suddenly becomes an anti-social rock'n'roller's
amp.

So it's not too late for me to be an anti-social rock'n'roller then?
Come to think of it, most of the good ones are about my age:-)
