I've got it on again... at about 75v...
How long would you leave it before you romp it up to 90-95?

I'm wondering if I don't see any filament glow with that tube... I'm going
to be tempted to  bite on the Ebay ads that just replace all tubes... the
set for this receiver is 69 bucks.

It's real hard to see the filaments in that tube John.  Wait until the room
