The 5670, 2C51, and 396A are the tube type for the Qinpu A-6000 Integrated Amp. I tried to order the W.E. 396A earlier today but the retailer is out of stock at the moment so will try again in a couple of weeks.

The Tung Sol 2C51 pair that I currently possess have 3 black plates per tube. The G.E. 5670 have 2 black plates per tube.
