I am sharing the ideas all the way here in the forum, however people almost always disagree with me ignoring my suggestions. Some even complain to moderators how I am wrong and how I offend them. 😀

Here is the result of following them. 😀

Edit: I posted the video to roughly offend those who refuse to learn.

I don’t know enough to be offended. I learn more that way🙂

I’m very good about following a schematic and buying the correct BOM. I learn by following excellent, specific directions. That’s what I need. You’ll get no argument from me. 😀
 
Well; I am not good in giving specific directions. I prefer to explain basics, so people understand how to do that, and why. When I taught electronics, I used a trick, I was giving a task to somebody to calculate something, or to design some schematic, then said that I need to go away to wet the sponge. I was standing behind the door, listening to their collective attempt to solve the problem, and only after they get quiet entering the class.
 
Cool. I was a teacher too. Every teacher chooses what point to enter the stream. You’ve chosen to enter further down stream than I stand. I’ve never even taken basic electronics. I’ve been able to “reach beyond my grasp” with the help of the kind people of this forum. Many thanks to all of you!

Seek Thermal camera has iPhone app. Pentode, with nested feedback loops. Gorgeous tube, one of the best for SE. Probably even the best one for up to 10W output power.

Can you please share the schematic of this amp with 6CB5A? I am really interested, I do not have your experience but so far I am been blow away by the use of vertical or horizontal deflection tubes and if I am not wrong this was used on color television's horizontal def....regards
