There is certainly a version of D-76 that uses 8 g/l each of borax and boric acid as a buffer. What I tested here was similar, but 2.5 times as strong. With borates, the buffering capacity may be cranked up a lot more than the pH by such combinations. The pH certainly did not rise with my 20-20 combination over that with plain borax, but may have been stabilized.
