tubes for tektron and primaluna


I'm in search of some tubes.
Have been recommended EH KT 90's for the primalunas (prologue 6 monos)which I can find.
but- for the Tektron 6j5 I am looking for Brimar ST shape grey glass 6J5's which I am finding very difficult to locate.
Any other thoughts or good contacts.
I listen to mostly jazz, funky soul, vocals and classical (also some pop/rock from time to time)
I'm also watching ebay with no luck so far.

thanks!!!!!
