I have had many requests for this subject video. I delayed since I did not want replicate similar information that already exists. So, I decided to make a cool test accessory, simplify the process. Also I wanted to point out some newer amp design hazards. Many techs/hobbyist have suffered injuries from being shocked while servicing tube amplifier, whether Guitar, Ham or home audio. Best thing to do is check, double check. Dont be in a hurry. I hope this info is of value to you.
