Yes! SS low and glass mid/high.

Keep the crossover out of the critical midrange. (somewhere below 350Hz)

RCA Raditron Manual Version 10 from the 1930's, especially pages 5 - 25 in the pdf file....

Bonavolta - Tubes for Newbies

If anyone knows a good on-line resource on basic Electronics (RLC, Kirchoff, Ohm, lentz etc) please post, this could be included as prefix to the above for a "crash-course in electronics".

Sayonara

The original ARMY 1952 tube manual is one of the best all around beginner sources I know of. My guess is that it was used for their Class A electronics school. It covers everything from physical construction, to electronics, to amplifier design, and does it in very friendly language. I don't see any copyright data in the manual, so I think it is free to share. Under the FOI act, it should be available to anyone.

Just to be safe, however, I'll post a PDF of it on my website: www.audiovib.net later today. You will see a new 'Reference' option show up under the "TIPS and TESTING" tab. Go to that option and download the Army Manual.

Cheers

Hi Wang.
Just read your post and would like to give my sincere thanks to you
for providing such a valuable tutorial on RCA Raditron. Its seems to be
quite intersting subject to me.
Thanks for your post and stay connect.

Hi, I've not read each of all the 105 posts but it's clear to me that there is, without any doubt, a lot of good material to study, if one is willing to do it. I also appreciate all the links and the references for books.
Theoretically I think I know quite a lot but my practical experience stopped when I was young and, when recently, I've started to build the Audio Note Kit One, after many years is not working 100% for a lot of problems of which, I believe, should be interesting to talk about.

Default Valve Course with lab materials kits?

Now here is a question, teaser, idea for some of those among us here who presently make kits, or sell parts:
How about a beginners course with packaged hands on lab work kits?

I know many many here in this forum are grand masters of Tube Wizardry and I'll just bet they could create some really great lab work experiments complete with built in "gottcha"
problems !!!

Though a long time solder melter I would just love to go back...rediscover all that magic when first cobbling bits of wire and attempting to herd electrons !

Now I have grandchildren full of wonder at that mysterious amber blue glow.... damn they've got good ears!!

Just a thought.




And Thank you to everyone here.

Default Found a awesome tube site !

just happened to come across this site that is filled with tube amp projects. the guy put some time into gathering these links (apparently 3,000 of them) and breaks it down to what tubes are the top 100 used in projects online, to how many different projects are based on a certain tube. Really cool site, also has a lot of other useful and interesting links. check it out... but be warned you find yourself stuck in there for a few hours.
Homebrew Gridlock. Web Page of Russ Davis, K3UH

site menu on the left is the tube section.

I like the idea. Another thought I had was to put together a normal kit using a video for description as opposed to a written manual. In the video one could talk through the reasons for choices and background as you build. Once the kit was complete, the builder would have both an understanding of the design and a good completed kit.




And Thank you to everyone here.

Yes. Pete Millett's newest could work very well.
Or an old fashioned step wise electronics learning lab that progresses from basic circuit and component operation to the power supply for Pete's amp. Then say an second lab kit that continues amplifier topology lab work ups concluding with his sweep tube amp.
Absolutely, a video DVD or internet stream.
I think it would be a great way for people to begin and for others to refresh and play, still others to teach.
That is how many of us began so many years ago with Eico, Knight, and Heathkit....
Mom's everywhere had burn marked tablecloths and mysterious silver blobs stuck to the odd thing here and there!!
