I watched your vids on this amp and followed your recos for tubes. Did the frontend first...WOW. Just received the Shuguang KT-88z's. The tubes were all marked 30ma. Does that mean the bias is to be set at 30ma. Sorry my first tube amp and have only had it a month ...so still learning.

No, that is just showing the matching point for sorting. Bias them as normal.
