I recently adjusted my bias to just under the recommended max of 49.5 ma, (recommended range 45-50)to my ears it sounds better the closer I am to 50 ma, I can lock all four KT88's in at that level with no problem, however, the next day after significant warm up,( one-two hrs.) I see where the bias has dipped to around 47.5 ma, everything sounds fine but I'm curious, is this typical and the bias will rise with extended play or could it be a sign of ageing Tubes? Thanks
