Thanks guys, I didn't bake the coil. From markmokris' post, I think I've got it right in that I used #38 wire, and according to my notes I did count 27 turns on it. The latest development was I had briefly bypassed the tickler with a jumper to measure DC bias on the tube, and when I removed the jumper it won't oscillate at all now. Maybe I've got some other issues yet. Not ruling out a flaky 36 tube, I recall it was testing a little weak on my emission tester.
