  1. Why was the video taken down?

  2. Apparently its “Commercially deceptive”. Crikey – sounds like the same guys who have Dave on their block list for certain components….

  3. So you can un-see something !
    (Was Looking forward to something Meaty -but apparently too spammy ! )

    Holy.. Why is the internet crap like kitties and a such is online, and the really interesting stuff is getting pulled down by youtube shitty policy?!

  5. Makes me wonder who made the claim. Anywho, it’s back up now.

  6. Ok, we saw a lot of CapXon caps in bad PSU-s and in other products, but Dave, please: it is time to do a comparison of caps. You have the equipment to take measurements, test some caps from various manufacturers, do some stress (temp?) on them, then measure again. Or do some teardown, what is the difference if any.
    I wonder why do we have to say Pana and Nippon is the best and others don’t? I think CapXon meet the specs. On the long term, it can be different, but who knows? If you use a cap in a well designed construction, it can not be a problem.
    So what is the base of we says CapXon (or others) is rubbish? It depends on the application. After a couple of years any manufacturer can be as good as the best. IMHO

  7. Nice video! Thanks!
    At the end ,you demonstrated the output signal (1GHz, 0dBm) from DSG815 with TEK MDO, there’re the 2nd harmonic and a 2.5GHz harmonic on the MDO screen, even you reduced the output power to -10dBm, the 2.5GHz signal was still there.
    I verified it by using RIGOL spectrum analyzer DSA875, the test result was that the 2nd harmonic is < -58dB (MDO shows -50.5dB), 3rd harmonic is < -69dB, there's not the 2.5GHz harmonic, suppose it could be from the the hardware of MDO. Please see my attached pictures. Anyway ,Thanks for your very useful teardown!

  8. I am no longer sure the place you’re getting your information,but great topic. I needs to spend a while finding out much more orunderstanding more. Thanks for fantastic information I was looking for this information for my mission.
