Youtube link.
(Have suggestions of videos to put here? Send me a message!)

Electricity and Electronics
Electronics Hobbyist Web Site GREAT Links! Don't pass this one by! It has electronic references, circuits, data, and repair info.
www.electronics-tutorials.ws/ has some great general electronics tutorials.
The
ARRL Handbook has set the standard for Ham Radio enthusiasts and communication
engineers through the years. You learn enough about electronics and radio
from one of these handbooks to build radio receivers, transmitters, amplifiers, and to get your FCC license! Great tube information!
This is the 1959 edition. Caution: 59MB - Large PDF File!
How to repair circuit board
problems, by billm. I use these same methods as well. Good guidance.
THE ELECTRON AGE - 100 years of progress in electronics - by Carlos Fazano
In case you missed the last 100 years. In English and Portuguese. Excellent!
ElectronicsTeacher.com - This portal is dedicated to Students, Amateur and Professionals in the electronics field.
I
have to point you to
Michael Hoffman, BSEE, at
Amptone.com.
I saw his site years ago but couldn't find it again until recently. His
site may have been my inspiration for starting this one. Be sure and
give him a visit. His site is really complete and full of good info,
suggestions and tips.
----------------------------------------
Vacuum Tube Knowledge
Tube Terminology for Dummies is the name, but it really
should be your first reading about tubes, especially if you are trying to fast-track the technical stuff to do something
specific.
J.B. Calvert's wonderful
and scholarly reference on Vacuum Tubes. Lots of theory and practice on
amplifiers, both solid-state and tube-based.
Fun
With Tubes! Great site! This non-commercial site is
dedicated to passing on and preserving knowledge of vacuum tube
circuits and electronic techniques.
Tube Amp Debug
Page by R.G. Keen. This page is designed to lead you through
debugging a problem with a tube-type guitar amp. Mr. Keen
knows his stuff. You can learn a lot from him.
Bonavolta's Tubes for Newbies Tutorial should not be skipped. Lots of good drawings and simple illustrations.
Amplified Parts presents 12ax7's - a comparison of current-production tubes.
The Tone Lizard Lounge site unfortunately is no longer reachable. I even wrote and asked him if I could mirror his pages, and he said the site was not down... well, it is.
If I ever get permission to post his pages, I will. Lots of great stuff there. Excellent for theory and practical information. Visit all his pages. Caution: Strong Opinions (usually right!)
TubeCAD Journal is an offshoot of Glass Audio, and is associated with the TubeCAD series of software packages. Loads of articles about tube amp design if you are interested.
