about the cat sl1 gain

I've tried to swap the ecc83s in the line stage for a pair of ecc82 to reduce the gain and noise in a cat sl1 (first version). Everything seems to work fine. Any suggestions?
Ken at Convergent Audio would be happy to send you information on how to lower you output in the line stage buy adding a divider internally. I lower the output in my MK 3 eight years without changing tubes.
