          That plagued me after I added the second 26 ..But it appeared so randomly it had me fooled.
          
          Now she's as solid as a rock , has plenty of gain with No pre. But with an active pre it just slams. What kills are those Hammond 125ESE's. They are such a bargain for bringing a project forward.
          
          I'm happy with the results of this experiment,I hope others will give it a try.
          
          Have fun

            If you could post (or send me) the final schematic.
            Observe, before you think. Think before you open your yap. Act on the basis of experience.
