Thanks for all of the help; my first attempt at checking bias and re-setting bias were successful -- and no injuries were sustained!
Biasing for new tube
I'm new to the tube world so I apologize if this is a no-brainer question for the experts. I am replacing one tube in a VTL MB 185 that arced on me. Do I need to check bias after the new tube is installed -- the VTL manual tells me to do so when I install all new tubes, but it's not clear as to the procedure when replacing a single tube. I'm getting the replacement tube from VTL. Any help will be greatly appreciated.
