I have a green stripe Mark III that I purchased new around 1989-90. For many years I ran the Master down very low so I could drive the preamp section for tube saturation and breakup in Rhythm 2. However along the way I learned the difference in preamp tube and output (“power”) tube...
Does anyone know the brand and model of the Mesa 6L6 str 441 as well as the other Mesa 6L6 offerings (6L6 str 440, 6L6 str 445, and 5881 str 425)?
Have any of you tried the 441 tubes in place of the 440?
Thanks for any input.
