Good day peeps. So I finally got my new tubes in for my Traynor. I wanted to try something different than the sovteks that were all across the board previously so I ordered jj ecc83/12ax7 pre amp and tung sol 6L6 STR power. The manual says to set the bias to 75 mV and the lowest that I could set the voltage was 77. Is this going to be an issue? Will it burn out my tubes prematurely? Will it damage anything in the amp? It does not make the banshee in a blender noise anymore and it sounds good, but I only ran it for about ten minutes because I am not sure about the voltage being a bit higher.
