With 12.17 vdc no delay signal present but all lights work and dry signal comes through. 11 vdc Delay signal came back
and is stronger than w/original psu, controls are more sensitive too. I liked the delay sound more with higher voltage, slapback delay was not so dull and more percussive and longer delays blended better to the clean sound. Voltages are from different supplies, I will test with an adjustable one and post results here.
