Hello again,
Thanks to Volker, DL4ZBG, he replied directly with the following link:

It is a nice description of many improvements that can be made for the KSB2.
However, I believe that I do have a fault in the KSB2 (Rev. D) or K2,
since I know it behaved differently years ago. For example, the ALC
shows 7 steady bars, no matter what power level I set nor how much SSB
amplitude is produced. Regardless of the power level set, the RF signal
is never stronger than 1 bar.
I will try to experiment further, and I'm open to get any hints.
Thanks!
Gernot, DF5RF

Hello list,
I recently tried to use my K2 on SSB. To my suprise, there was very
little output. Even with full power it only showed the first bar. I
did some SSB QSOs during the first years...
Digging deeper, I found the DSB signal showed a Vpp of ~1V, but after
the filter the SSB signal was only 20mV or so. Is this kind of loss
normal for a 7-pole filter? If not, any hints how to repair the filter?
tnx es 73
