How to use a Digital Oscilloscope...to test your tube amp! AT THE BENCH!

Video Description

The previous video detailed how I use the multimeter to test voltages in a tube amp, this clip deals with the Oscilloscope. I cover Scope basis, generating a test signal, tracking the signal through the amp and finally how to measure RMS output power. Our test amp is a Mojotone 45 kit that was built by a local player and brought in to me for completion. 0:00 Intro 0:53 Scope basics 6:43 Signal generator 9:22 Connecting to the amps input 11:35 1st gain stage 14:00 Volume wiper 15:42 Mix resistors 17:03 V2a gain stage - AC Coupling 20:03 Cathode follower - tone stack in 22:50 Treble wiper 23:27 Phase inverter in 24:05 Speaker output 26:24 How to measure output power 28:32 Outro - possible mods? https://headfirstamplification.com
