Probably nothing new to some of you, but here's some good tips all rolled into one video.

I like his explanation of heart valve operation and lock-up.

A good primer for newby's and always a good reminder for old heads as well.

Done in a personable way.

Always good to review the safety procedures. Thanks for the vid.

Working on the amp while "hot" is a completely different set of rules.

Here is one that often gets overlooked: Remove your wrist watch and any rings when working on a "hot" operating amp. A conductive watch or band or ring can literally weld your wrist or finger to voltage inside the chassis! Your jewelry also gets very hot when this happens......

"...can u lock it at the top of the thread?"

Good idea. Very simply stated with excellent emphasis on appropriate details. Good job. He's got me convinced!

Very good video. I always knew you stand a chance of stopping your heart with a high voltage shock going in one arm, thru the heart and out the other arm but the thing I did not know was why it happened sometimes but not others. This was a real eye opener. Thanks for posting this video

Thanks Pinetree!

I've seen a number of videos trying to explain this procedure.
This one is absolutely the best! :)

Here's the answer to a frequently-asked question regarding amp safety: how to install a three-wire (grounded) AC power cable in a vintage two-wire amp.

Remember the polarization scheme in a grounded AC power outlet; the wide slot is neutral and the narrow slot is hot.
