When it comes to HF AC heating, I'm bothered by the capacitance between the filament and cathode in IDH tubes. It's not clear to me that this can be ignored, that a null can be achieved or maintained. All things considered, it seems there might be less risk to the DC approach.

It would be interesting to try all three approaches and see what you prefer when you listen. I'll have to try it sometime next month when I am back in town.
DC
AC 60 Hz
AC whatever MHz

I am off to India for three weeks, but I think I can do this when I come back using my old Tubetaster line stage if I modify it a little. It is a work of art and a joy forever.

And what, pray tell, will you be doing in India?
I have been retired for 7 years and each year in addition to other travels, I go off by myself for some sort of trip, usually for a few weeks. My wife enjoys the period home alone, particularly the quiet. When I meet various couples during my journeys and they ask about my wife and I mention her attitude, a light comes into the wife's eyes and they understand precisely.
I am just doing a 22 day tour in northern India. When I was in Turkey two years ago, some other travelers told me to go there. I will blog the trip at the link below.

Sounds like you are really enjoying your retirement. Have fun. When you get back remind me and I will show you how to build a squirrel proof bird feeder. As with most things, when you finally figure it out it is very easy to do. I battled them for months until I finally came up with my current design. No problems anymore.
A 25 Cal, Benjamin Marauder is a much more satisfying feeder protection device, and squirrels are waaay too tasty to ignore...:)
cheers,

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
They like to chew on the house, so I've been knocking them out of the trees with a Gamo for several years. Don't care to eat them though...

The quarter bore Marauder allows a significant reach increase over springers, gas ram or otherwise...:)

We have a bird feeder outside our kitchen window, on a post. My wife has an eternal battle with the squirrels who have managed to either eat or climb around any barrier she places on the pole to prevent their climbing up to get the food. Which is ridiculous on their part, since the birds splash food all over the ground where the squirrels are welcome to it. However, they are greedy little bastahds.
Watch for future posts. When Ray gets back from India I will posts pictures and a description of how it's done. Easier than one might think.

Late one night I was watching TV in the total darkness, when I perceived something run across the room between me and the flat screen, very very fast. And it disappeared into our living room. We subsequently figured out it was an animal that periodically was invading our pantry for food while living in our chimney. My wife eventually trapped it in the pantry, using a Have-a-Heart trap provided by our hardware store. She drove it out into the country and released it. It was a bona fide flying squirrel. She thought it was so cute she hated to let it go. Just like Rocky.

Now that would be very interesting. Does it involve zapping them with high frequency AC?
ray
Now there's a thought!
Sounds like fun! I visit China every few years, usually for a month or so. It's great to get a different perspective on the world once in a while.

My experience is that every country has something different and interesting.
And of course, 90% of the people I meet are very helpful and friendly, especially when I smile.
