I use svetlana 572b's in my 811h. They work great! However, the svetlanas are
not as good as other brand tubes and won't hold up well in amps designed for
572s. They will work well in the 811h amp as the amp will no push the tubes too
hard.

I already dropped the money on non-refundable NOS Svetlana's though.

Drax,
I was told not to use the Svetlana as the replacement for 811a tubes. Taylor
572b is a direct drop in replacement. I cannot recall what the procedure
is with Svetlana. If you can get the Taylor's, do so. I did that on mine.
Flawless!
Good Luck
