How does tube bias affect tone
WebNov 21, 2013 · Changing rectifier tubes can have some sonic effect, however, and can have an effect on the feel of the amp. For one thing, one rectifier tube of the same type may drop a little more or less voltage than another - the higher the B+ voltage is in the amp the cleaner / harder it'll sound compared to lower B+ voltage. http://aeaaudio.com/why-does-changing-tubes-change-the-sound/

WebThis allows you to use unmatched tubes but bias them evenly. You can even run a 6V6 and a 6L6 power tube together and bias each tube properly. You can also fatten up the clean and overdrive tone by intentionally mismatching the two tubes' bias which increases sweet sounding even order harmonic distortion. An increased bias mismatch can cause an ... rtd discountsWebNov 13, 2007 · At a certain point this will cause a more positive voltage at the cathode which then cuts the tube current (compression). As the note decays, less voltage is drawn through the cathode resistor which then causes the tube to draw more current. This is the sustain or "swell" that you can hear in some cathode biased amps. rtd district shopsWebMany of us have spent a great deal of time & money swapping out vacuum tubes in our amps in a quest for "better tone."
