Phono tubes must be rigorously tested and specifically selected for low noise for best results. And this goes double or tripple if we're talking about MC phono sections. There is SO much amplification of the signal going on that even the slightest bit of tube noise can come out the other end sounding like a roaring ocean. If the Tube Depot did not specifically state that they were phono quality and you did not specify that they needed to be phono quality, then you very likely did not get phono quality. Do you have any other non-phono uses for them? If yes, chances are they'll sound okay in lower gain appliactions.
