    Default C-J MV-52...bias problem

    Finally got all my tubes installed and went to bias the 6ca7's and have run into a problem. Locations 5 & 6 biased fine but 7 & 8 won't. The red light will not come on whether i turn the screw all the way clockwise or counterclockwise.

    Suggestions??

    not familar with that amp,, whar did you have in before? were you able to bias them? Have you tried swapping the tubes? Maybe a bad bias resistor?
