You know, I'm just pointing out that there is another option now. I have a small box of NOS euro ef86s including mullard, siemens, telefunken and GEC, and a couple of 7308 PQs, so I'm sure I'm going to find what I want somewhere in that collection.
I also thought there was some issue with the ef806 in the Eros, but I don't remember what it was. Thanks for the pointer though, someday I may get to try all these options.
