    While practicing the other day, I decided to crank the blend knob (I keep at clean, 99.9% of the time.) As I turned the knob more and more from clean to grind, the volume started to fade until there was none. My first guess is that the tube went. Am I correct in this assumption?
     
  2. Try to change the lamp. I have a RPM1 ( the ashdown preamp )
    If you turn potentiometer at solid state and haven't problem i think the problem IS the lamp.

    Thanks. That is what I thought. I emailed Ashdown also, but I haven't got a response as of yet. They are usually very quick with their responses. I just wanted a second opinion before I opened up the head.
