Tube Amp Theory: Uncle Doug and his dog Rusty

WARNING: Never attempt to open up your tube amp chassis or repair/modify it in any way, as lethal voltages may still be present for extended periods after the amp has been turned off and unplugged from the AC wall socket. Instead, take your amp to a qualified technician for inspection or servicing.

How many times have you searched youtube for concise, accurate and clearly-explained information about a topic that’s important to you, only to be greeted by some frenzied bozo desperately trying to squeeze their fifteen minutes of fame out of the internet like dregs from a tube of toothpaste. Music blares, graphics swirl: you’re implored to subscribe in booming robotic voice. Ok, no problem, you’re on a quest with a mighty thirst for knowledge and willing to put up with whatever it takes.

You wait, wait, wait some more (2 minutes in and this fool is still talking about his holiday in Bermuda)….still nothing. Fast forward a bit. Was that something there? Rewind. You discover 15 secs of (inconsequential) information deeply nestled within the 9 minutes and 53 seconds-long “tute.” Unfazed, you gain your composure, click on the next offering….another bozo…uggh! (Yes, I’m aware this introduction has similarly delayed you on your quest, but be patient…treasures abound below).

If your topic of interest is tube guitar amplifier theory, then have a look at these videos by Uncle Doug, a former teacher who actually knows how to…..wait for it…teach! But don’t go thinking you’re going to fall asleep without all the usual CGI generated graphics and (phat) Techno beats supplied for those of with the attention span of a….(no need to finish that, those concerned would’ve moved on already), Doug’s diagrams may be drawn in pencil, but they’ll address most of your burning tube amp theory questions, and furthermore, Doug’s ever-faithful sidekick, cameraman and general bon-vivant Rusty will keep you in stitches exactly when you find the need to take some time out.

So, I hope you find these tutorials informative and enjoyable. Happy trails.
