I bought an Orange Dual Dark 100. There are noise, "pops", drop in treble and volume and channel A died. I changed the position of the valves, it worked, seemed like a "bad contact" and both channels works, but still there noises and instability, if I turn the Attenuator or change power it starts again, so I decid to try a complete new set of valves (hoping that the problem are just the valves).
(I have warranty yet, but I live in Brazil and bought in USA, so...)https://youtu.be/uYlbdy87gv4
Besides that a question: the fist roll of tubes is JJ-ECC83s/PM-ECC83/JJ-ECC83s/PM-ECC83 it is original from factory? Or they already changed the tube before me? Orange uses always just PM or mix like that?
Thanks a lot guys!
