Hi, since you mentioned about building BH, I would like to ask you if could to help clarify some information, because to build KGBH not easy task. I hope it’s just me missing something.
The main problem is the PCBs. To order them I need files. Kevin said that he can't provide them because of the agreement with Justin, who designed them, but Justin willing to sell the boards. Which is very good, because it will be cheaper and easier just to buy them from him? I ask (emailed) Justin, asking if he have them, and looks like my message was lost in tons of other emails, from angry headfirst who were waiting imptient for thier builds, KGBH SE included .
On the other hand I heard that in the near future will be new redesigned two boards PSU (one per channel, not two on the same board), which be able to provide 500v. Plus the original designed schematic has been tweaked, and is now KGBH SE.
So I decided to wait and hope that all of that will be available in the near future to regular DIYer.
Few more questions .
What is the difference between SRD 7/mkII and SRD 7 Pro.
And is it possible to lift bias on my SRD 7/mkII to 620-630v to use it with recabled ESP 950?
Thanks!
