    If you are just changing the preamp tube, no bias setting is needed. If you change the EL-84 output tubes, if the tubes are bought as “matched pairs” (same gain in each tube) bias settings, on the average, don’t need to be done, and can’t be done on this model. If the amp sounds dull and cold after the change, your best bet is to re-bias the output tubes, however, that should be left to a local shop, that has a great reputation. This would involve modifying the actual output circuit, to make it variable bias, instead of fixed bias and that is best done by an experienced Technician.

    Even if you just change a tube, beware!! You are dealing with High Voltages that can kill you!! You’ll be playing a Harp in Heaven, instead of a Guitar on Earth, if you get zapped by over 385 volts of Plate voltage present in the Output stage of this AMP :O

    Make sure that the amp is off and has been unplugged for some time, as the power supplies in the Amp can have lethal voltages present, even after three hours or more, before you change out any tubes.

    Tung Sol Tubes make most any amp sing, go to http://www.tubesandmore.com and take a look.

    Good Luck!!
