Thanks kagliostro ! I found a few of these NOS cheap awhile back and got a few to try out in the future.This table willl be a big help.

Consider that in old amp the ef86 settings (as V1) were hot

so the tube can more easily result microphonic

lowering values sometime is a good idea

consider also to use dampen rings on the tube and/or a dampen socket
