Sorry, I don´t follow you Mauri. Beats me what´s peculiar
about a QBL5/3500.
For size it´s smaller then a 4-1000A and not much bigger
then a 3-500Z, just a little taller.
Do we have to run the tubes at maximum ratings? Is this
why there are so many wide Italian stations on the bands?
No you can´t work GG with this tube so if that makes it
peculiar I´m with you otherwise I´m lost in space.

Most of that style amplifiers are actually using the very peculiar
Philips QBL 3.5/5000 that leads to say much bigger amplifier, two times
or more, than the standard amateur market Alpha's or Ameritron.
It wouldn't be wrong to check what happens at the IMD products with the
QBL 3.5/5000 when pushed to it's full drive and plate PS max ratings.
All considered, I suspect the reason to use a G2DAF styled conf. with
an available tube (lower price than other tubes of that power) that's
very peculiar and can't work GG is a consequence and not the choice for
better performance.
