You're a generous sort, Mprime. Very cool.
I have a pal with the same preamp as yours and he's looking for NOS tubes for it now. He has tried Ken-Rad black glass but found the sound congested ; maybe they were not the staggered plate version.
I have a pair of Brimars for him to try when he gets a chance.
