Excellent vid Dave! Glad to see ya back in action. You mentioned having a lack of time for videos on The Amp Hour. Understandable. Glad to see this tear down posted.

awesome bit of kit!. I am pretty sure I have or had an LCD the same as what is in the Power Analyzer, it came out of a print server PC that lived in the bottom of a very old color A3 copier. pretty standard LCD module.

Why would 11 people give this the 'thumbs down', what did they expect to see when they read the title, boobs, kittens on LSD or maybe they thought "Voltech PM300 Power Analyzer Teardown" meant 'how to get free food from McDonalds' ?

It's a simple and accurate title from EEVBlog, a straightforward video showing exactly what the title describes and a fairly comprehensive commentary going over the Voltech PM300 Power Analyzer in plenty of detail, all in good focus with good lighting and even explaining the possible reasons for design and choice of components.
What else would it be ? What else would anyone expect ?

I'm completely baffled !

Those green caps made me nostalgic. I grew up seeing those a lot! Nice to see some good old boys' design... thing's gotta be near bulletproof with all those TTLs.

The first time I saw a 3-phase power analyzer it was back in 1995...it was on a big cart and had a PDP-11 frontend.

I'm always excited to see a new eevblog video!

I'd like to see you demonstrate this unit.

Maybe there is two transformers to take isolation to specs needed - coil to coil arc over would be messy. Otherwise quite standard 5V logic chips there. Keep up the good work.

.22J 6kV -> 220n 6kV Just a tip, I know it's hard to comment when filming

having a centronics printer port in 2002 seems baffling, sure you could still get them but they were well on their way out

You obviously don't do much work on consumer products Dave, funny how you opened the thing! A lot of VHS decks, CD players, set top boxes, etc. used this type of box, you take out 4 screws on the bottom and pull a bit on BOTH sides at the same time (not just from one side lol) and it comes right out.
Great video, I used this type of analyzer before but never bothered to take a look inside. I still kind of like this type of through hole construction!

damn that design looks 30 years old, you could probably do it three or four parts now

Dave, I'd love to buy that one off you! I could really use it daily for my electrical work. Would be far more superior then my insulation meter!
