Meteor Noise: the mystery (Trailer)
มุมมอง 2464 ปีที่แล้ว
Once thought to be the product over an over-active imagination, synchronous meteor noise is a super-rare, capricious and mysterious phenomenon studied by only a handful of scientists around the world. The mechanism to explain the sound continues to remain elusive.

Australian based cinematography (4k 4:2:2) with lighting kit & sound. Creative, collaborative, patient and intrepid. Love a challenge. International projects welcome. Skill-set includes editing, colour grading, audio-sweetening & music production. E: matt@studio20.cc
I have the same unit and had EXACTLY that cap blow up on me too. Thanks for pointing out, I looked around quickly but missed the other RIFA caps. I'm gonna have to recap it soon i guess, just to be safe. I love this scope and want to keep it around for as long as possible!
Hi great video, i have the same issue, I want to replace the old caps, can you share the replacement caps you used, finding it hard to find equivalent. Thx
For the electrolytics I used ordinary like for like values that are usually readily available. For the Rifas I made sure to replace Class X with Class X and Class Y with Class Y of the same value. I think I sourced these from a large component supplier like Element14
Thank you!
I just bought a 2215 that is humming and giving off electrical smells. I will check the rifas, and other caps. I think there is something else going on too, as no measurements are working, so may need to replace some transistors too. thanks for sharing!
Hi, thanks a lot, I just get a 2215 a month ago, it looks very well, but I will start replacing all the old parts as you show on this video. ;-)
Very observant. The original cap was the large Sprague & had a metal case with 3 earth lugs and the positive lead. It was replaced with a two wire electro. The links just tie the earths together
What going on there at 5:00 with the jumper wires? Traces lift off the board?
I knew the RIFA capacitors were a problem in these scopes, but not the IEC connectors! Thanks for making this video because it might just save my scope from an explosion.
Love the video!
