Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: And I guess if you HAVE to parallel plates...

A lot of these arguments fall apart for this very reason. The biplate 2A3 is bad because it is essentially two discrete tubes in parallel like the 152TL. By that same logic, the 45 is bad because it is also two tubes in parallel. The thing that finally sold me on this was comparing the EC8010 to the EC 8020. Both have the same Mu but the EC8020 has double the gm which translates to 1/2 the Rp. If you look at the tubes the EC8010 is simply an EC8020 with only one plate rather than a plate on either side of the cathode / grid structure so it can be argured that the EC8020 is simply a pair of EC8010's in parallel :-)
