Do you realise that all the links in your signature bring me back to this same last post/page?
I have modified the signature links (removed page numbers and left only post numbers). Please check if this works. 🙂
Andrew,
pl go to your user CP, and under edit options, change the following
Number of Posts to Show Per Page: set the forum default.
I think that might fix it for you.

There is a way to set up a link that ONLY works for other Members who use the default settings.
There is a correct method to insert a link that works for all Members.
You and two others can now see your links going to the correct pages.
It's Prasi that wants us to be "defaulted".
Hello guys.
Did anybody tried to test PeeCeeBee with differents IMD tests?
I tried one (on the amps I have, still waiting for the PeeCeeBee pcbs to arrive ) that is :
6.5k -5db with 7k -17db.
And I found very interesting results. but I have no idea how relevant is a test like that?
how common is to have music with this kind of reproduction pattern.
Thanks

Hi brunogiovs.
I haven't done an IMD test for the PeeCeeBee. There is some relevance of this test especially when the amp in question has too low slew-rate. But PeeCeeBee versions have 60-70V/uS which is much more than sufficient for the power output of these amplifiers at the highest frequency of interest. The V4 increased the ceiling further to 100V/uS so IMD is expected to be barely a problem. The many listening tests also indicated the same, i.e. effortless production of music without any loss of clarity anywhere in the audio band.

Interesting. and more interesting aspects of this test was when I increased considerable the bias on one of the amps under test.. it start to perform much better. I got really surprised.
Thanks
Yes in some amplifiers high slew-rate (low IMD) almost directly relates to output stage bias.
thanks, If I use the PeeCeeBee with lower voltage let say. +/- 25v.
does it needs modification to keep a good bias on the drivers?
Thanks
