Congrats on your new preamp.
However, I wonder about the 6H30P tube.............. with it, one essentially can do little, if any, tube rolling (of which I'm a fan). BAT pretty much introduced the tube to the industry in the previous century and swears that the Soviet era ones are noticeably better sounding & higher quality then the current Russian tubes. However, finding NOS Soviet era 6H30P tubes costs as much as finding NOS Bugle Boys and similar tubes ($$$$). While it is easy to understand the marketing use of the 6H30P by BAT when they first come into the industry, I've never found a satisfactory answer as to why ARC, C-J, Rogue, etc., have moved to the 6H30P in recent years.
