Default Tube Question, what the....?

Does anyone know of a potential website containing tube data. What I really need is something explaining what each Pin does on a EL84 and 6CG7. Still new to Tubes, trying to restore an old amp...well ok, modifying it that is :>)


Basically, trying to remove any old un-ness. wiring from it. I have another thread about finding old amps, people giving me old amps etc. This one was givin to me by a buddy, caught up with him this weekend and he told me it came out of an old console type system. It's not the best/worst amp going, but hey it was free and well, I like to play.

I would suggest that you get a tube manual. I have 2 RCA manuals, and they are a big help. Go to eBay and try to find one of the later issues.

Default Datasheets

You will find a good source of tube datasheets at:

http://www.duncanamps.com/

This site has a search engine where you can input the name of the tube you want information about.
Hopefully you will be represented short data, complete datasheets, pinout and schematics for the actual tube.

You can also try:

http://www.mif.pg.gda.pl/homepages/frank/index.html

Here will you find a lot of good datasheets published inn PDF format.
Mainly datasheets from Philips, Mullard, Sylvanina, Telefunken, RFT, Marconi and Tungsram....

Thank you very much for the reply...great sites, lots of info.

Think I should do some more reading in regards to the function of tubes...isn't this fun!

Any good books to read on subject...hum wonder if they have a "Tubes for Dummies"?

Default READING UP

Hi,

If you want to do some reading here's a good place to start"

http://www.radau5.ch/basics.html

You can download these files and read them offline,whatever but you'll need Adobe's Acrobat reader.

http://www.adobe.com/

No doubt there are a myriad of other sites with interesting info that you can download.

If you're using ADSL or some other fast connection it's easy to mirror entire sites and burn the interesting ones on CD.

I'll need another six months to catch up and I'm still finding interesting stuff while trawling.

Not for "dummies" though.

Happy reading,

P.S.Rino,if we don't hear from you in the next couple of months we know what you're doing,right?

Thanks for the info...again :>)

"P.S.Rino,if we don't hear from you in the next couple of months we know what you're doing,right?"

He he he, Frank you know me all too well. But you guys won't get off that easy...I'm just getting started with DIY fun!

Actually, my employer is shipping me off to California for 3 weeks in December. Though, be it limited, I will still have access to a comp. :>)

If you want an introduction to vacuum tubes you can try this page:

http://www.eecs.umich.edu/~mmccorq/t...roduction.html

Here will you find information about how a tube works.


You can also try Svetlanas "How a tube works", even if this site officially is down there is a backdoor that you can use.

http://www.svetlana.com/docs/tubeworks.html


When it comes to books I recommend:

Valve Amplifiers by Morgan Jones
Tube Audio Design by Bruce Rosenblitz
