Optransformer for 6B4G?

Planing an 6B4GSE amp and I have an trafo (output) wound on a EI84 core that I might use (have used them before).
I would like to use some trafos from Lundahl but there to expensive for me right now,so I wonder is there some Good! output trafos out there that don´t cost as much as the Lundahls?
 
UBT-3 from One Electron is supposed to be pretty good. I have a pair but haven't tried them yet.

They are rated at 15W so they are a bit over-sized for the 2A3 and 6B4G, but should be fine.

if I were winding an OPT, I would go with a 1.25" stack of EI-100 instead of EI85. I think the EI-85 winding window is going to be really tight.
