Seems quite a few names come from that plant and both Tung-Sol and Mullard new productions turned out to be pretty good stuff. The Mullards sounded good in my Blackheart and the Tung-Sols improved V1 and V2 in my Alchemist.

Yea I like swapping tubes and play for a while then I'll know what stays. The Blackheart did had the Tung-Sols along with Sovtek MGs which was the best set for it. Now the Tung-Sols are in the Bogner.

I'll check out the other tubes and who knows, next month I'll get a set.
