Unwinding a tiny transformer

I don't know how you do that at 4am Clive, seemed quite normal to me. :-)

Initially it was because that was the only time I got peace or time to do stuff, but now it's just due to non-fixed working hours and a tendency to work late into the night.

Primary too low to measure accurately. Secondary 18 ohms.

There are parts where you do talk and sound slow. Apart from those moments the video is ok. I might not opt for a reshoot but maybe think again next time you want to records a video when you are really tired. Sometimes it is good to take a good night sleep.

Sounded fine to me. I was distracted by the subject. I like seeing this stuff.

Thanks, Clive. That's a pretty usable datasheet. The 10kV rating could be the secondary breakdown rating. The output might go higher than 6kV with reactive loading. I wonder what the melting point of the wax is? Since there's no secondary interwinding tape, the enamel must withstand two layers' worth of voltage == 1.3kV @ 6kV output. That's quite a lot.

Mike Page

I guess they are semi-automatically wound, ie a person with a winding machine. Manually applying the different layers of wax and tape. Hmm not sure I've put that very well.

Dr Andy Hill

You sounded just fine, Clive. Thanks for an interesting teardown.

Sounded fine to me as well. It's amazing that the same kind of construction used in 1.5 volt guitar pickups can handle that kind of voltage. I learned about wax dipping pickups from a Guitar player interview of Eddie Van Halen. The wire looks similar, resistance on my pickups was generally around 7 ohm. I'm curious what it is on those little spools, not that I need an answer.

no need to redo anything :)

Sounds as good to me ; maybe build an electron microscope for some high voltage fun.

Is a 04:00 start the only way to avoid Ralfy walking into shot?

AlfaGuy

I don't see any reason to re-record it. Sounds fine to me.
