Hi Albert,
you made me doubt about the PG506 now :-)
I would not like to have calibrated the 7A16A trying to compensate for the aberrations of the PG506 itself.
In the weekend I'll check the fast rise output of my PG506 using the 3S11/3T77A and also with a 2 GHz Philips PM3340 that I received a month ago (fully functional, like new).
I'll post some photos as soon as possible.
