  • Bias DSl with JJ's?

    So I am going to make an attempt to bias my Marshall DSL 100 watt head after I install a brand new output circuit board.  So what is the best meter rating for the tubes(JJ's) el 34s.  I have been told the tubes should be around 90 but going at 80 is okay---any input woudl be great--thanks

    80 is about right for most DSL100's . They do run hot. My tech had it at 70 but I put it back at 80..

      Do you like the loop on the DSL ?

      - IT was great for me at first - but then then the muddiness got worse--so the board is being replaced
