suggestions for 300B tubes
Does anyone have a suggestion for a pair of 300B tubes for Welborne DRD amps? I prefer liquidy midrange to bass/treble extension if this is an either/or. Also, price should be within reason (i.e., W.E.'s are too expensive.)

Tubes I have heard good things about are the TJ mesh plates, and some of the sophia electrics (these are perhaps the same tube?), as well as the KR audio and emissions labs.

Also, any thoughts or suggestions on where to get them ?

I have both TJ mesh and EH gold grid 300B's. They both sound differently but I like them both.

when using relatively expensive Tubes anyway, then Id opt for the best...which is without doubt the KR300B XLS. They are more expensive than other tubes, but on the other hand theyll last min. 3-4 times longer because of their build-like-a-battleship-quality and has much more dynamic headroom than any other (20-25W against app. 8-10W from a mesh-type in SE mode).
Dont use mesh plate types. There is no good technical/sonical reason at all for the usage of a mesh instead of an massive plate (well ease of building and production costs are good reasons...but not for the end-user). Less stability, less wattage, less dynamics, less lifetime....more light (if You want that, get Yourself a proper lamp ;) ) more heat, more problems.
