Updated chart for Hickok TV-3/u or 546?

Hi,

I picked up a super cherry Hickok 546, which the internets say is identical to a TV-3/U (not a-b-c). I see some folk have posted settings for individual newer tubes here and there, but I'm not finding a full updated chart. I think my odds are long, but has anybody seen where such a thing is compiled?
