Is it just faulty memory or did not Svetlana come out with a "beefed"
up version of the 811A?

Also, and I'm trying to remember the 2 811A amp I home brewed
thousands of years ago, but I seem to remember some "tech advice" from
somewhere that said to pay special attention
to the resister/coil used to feed the HV to the amp. Something about a
spurious emission?
