RE: Why are 6sn7s noisy in one preamp and not another?

I retube a ton of gear and certain Rogue products have a tendency towards this problem. It may be that this circuit is designed around a lower gain or quieter new production 6SN7. So it is a different design but I think a case could be made for the Rogue being a bit of a problematic design. To be fair I have seen this in a few other models from different manufacturers.
