Title: Tubes yah some people still use them
Post by: Asellith on June 24, 2009, 12:27:41 PM
So I am taking a study course for the General Radio Operators license for work. Some of these books are killing me and they are all about tubes. I was wondering if anyone knew where I could get a list of all the equations that pertain to tubes. I have similar lists for transistors and mosfets in my engineering books but they don't talk about tubes.

Also before you all start jumping up and down screaming no one uses tubes anymore, I am a radio engineer and we are some of the few who still deal with them on a daily basis. Most of the time our tubes are bigger then your head and have thousands of watts running through them but they are still tubes. And for the record to all those people who told me tubes where just like transistors your wrong dead wrong. Concept the same execution and equation wise they are totally different. So if anyone has some info on a place I can get this without plowing through 8 or 9 of my books from CIE to find all the equations let me know.

heres a link with some basic circuits and a list of equations

heres a forum discussion on tubes (saying that little or no math is really required)

also check this site for more reading material on tubes

Tubes are starting to come back into fashion for stereo's as they provide better audio quality (guitar amps usually run off of tubes too)

Ive seen the first site in a dozen google searches but my company firewall prevents me from seeing it. I'll have to check it out from home tonight. thanks for the links
