The 650 is very similar to the 700 & 707 (who's manuals are available on the BAMA Mirror site), I suggest you try the settings listed for one of them. B&K updated their tube manuals frequently so many do not have the later model tubes listed. I have an original copy of the final 650 manual coming this week, if it has any of the 6dj8 family tubes listed I will email you the settings. The only thing you would need to determine would be which 9 pin mini socket to use, which shouldn't be too difficult as all of the pin 1's, pin 2,s, etc., etc. etc. on thru pin #9's are connected in series to one another.
6922/6DJ8/E88CC on B&K tube tester
Just bought a B&K 650 tube tester. I have lots of 6922/6DJ8/E88CC/ECC88 that I need to match, but the booklet that came with the tester does not include an entry for that tube. I also tried looking up 7308, no luck there either.
Does anyone know which socket and setting I can use to test the 6922 variant? Or what other name does 6922 have?
