Electrical Safety With Old Electronics

[@deadfreightwest5956]

6:26 - I think you meant lead and _tin_ not zinc. I had a hot tub panel fail because whoever soldered the spade connectors used acid based solder. Rotted the wiring all away.

Hello From Kingston, nice to see another canuck with an affinity for vintage kit :)

Great video, Jeff. Thanks for sharing--you've provided really good guidance. You may want to share some of the references you used to specify dangerous levels of ac and dc voltage and current, as I'm sure that some folks will want to do more research in these areas. Thanks for all your videos.

I will keep my language clean, but I could certainly say more. Thank you greatly for this video. It is an extremely important example of the far too few on e-safety. As for all those [deleted] who would have such discussion censored for [deleted] reasons, [deleted, deleted, deleted •••]. May they live longer than they deserve.

Excellent video but I must respectively disagree with one of your cautions at 12:35. If you are using an isolation transformer with a hot chassis device, there is no danger in connection of test equipment grounds directly to the chassis. In essence, using an isolation transformer with a hot chassis is no different than a device with a power transformer and a half wave or center-tapped full wave rectifier. In either case part of the secondary winding is tied to ground. Now there is a potential measurement problem with some hot chassis devices. In some cases the chassis was floating DC wise but grounded RF wise through a 0.1uf or so capacitor. In this case you wound want to connect the test gear to the signal ground and not the chassis.

Some excellent advice in this video Jeff! One thing I must mention if you are going to be using a certain electrical wall socket make sure it is wired correctly. I came across a socket that had hot and neutral reversed ! A socket tester available at most hardware stores with three neon bulbs confirmed this. I'm glad I never used that particular outlet for anything other than a TV or computer, both with power transformers.

Great advices. I did restore a reel to reel player - as in changing old belts, new cogs on trip counter. But I didn't change any old electronical components. It works very well, even if it is from 1969. I wonder if it is safe to use, or it could cause a fire. Not much knowledge on electrical components. 😮

Excellent video! Very informative and highly interesting. Thank you

I remember to this day touching both terminals of a Lionel transformer. It tingled!

Excellent and very important information. Prevents magic smoke escaping (which is what makes electronics work!) and nasty bites.

Excellent video!

Hi Jeff - I have a Heathkit GR-21 and live in the San Francisco Bay Area - do you know anyone local that can help with some mods/repair? I have such little knowledge about this stuff and looking to make it function well once again.

[@jefftranterics]

Unfortunately, no. I don't even live in the USA.

[@justinlindenberg]

​@@jefftranterics Would you do a phone consult? Seems like you're the only person that knows about these things!

On the 13th of August KZbin turned off email notifications for computer users. There is very little point in being subscribed, if we won't get notified... that stupid little bell on in the KZbin screen isn't going to do it. Every creator, who wants to keep his subscribers, should insist that KZbin brings these notifications back. (and kick the idiot that dreamt up this daft idea out on the street!) Paddy
