Defpom's Electronics Repair
Новая Зеландия
Добавлен 28 ноя 2008
I do electronics repair, fix test equipment from Fluke, HP, Agilent, Keysight, Boonton, Rohde & Schwarz, Racal-Dana, Philips, Marconi, and many more, as well as doing other general electronics repairs on whatever I get on my bench.
I am keen to work with brands to review products, so get in touch (I will only reply to brand owned email addresses, no gmail etc. there are too many scammers out there)
I do reviews, mailbag, projects, Arduino, CB radio, and fix electronics, or show anything that I happen to be fiddling with.
I believe repairing items and not contributing to a wasteful throw away society is essential, I want to work with companies that support repair, such as Keysight, Fluke, or any other manufacturer that publishes service manuals and diagrams, or that provide repair parts (so no, not you Apple) !
I upload new videos every week, so SUBSCRIBE and click the BELL !
Anyone into radio will probably know my website: www.radiomods.co.nz
Thanks for watching!

That spectrometer looks pretty cool! I have been using an Opple Light Master 3 (ams OSRAM AS7262 sensor) to measure the CCT, CRI and delta u,v of various torches. There aren't a lot of options at this $50-100 price point for hobbyists.
Nice death adapter in the spectrometer kit for the CFL :)
Hi I have problems to understand your dialect you talk to fast and berry confused if you do this tape of job reviewing tools you have to learn speaking better
Just forked out some dollars and ordered the Little Garden Spectrometer. Will be interesting playing with it. Keep up with the videos, Have a good day
ROFLOL. The cat had something important to tell you, even more important than your Mailbag Monday. 😂
Buy a proper knife for unboxing
@@jw200 the RAM knife is used for a reason, far less likely to damage something inside the package (I have a nice camera bag with a big cut through it from before I used the RAM knife), AND it is a gimmick for the video, I have explained this many times, I have a proper knife just off camera for tough packages.
Man you went to town with the fan bearings 😂
Miauuu Mrrrrriau 😀 Got one self, i love her, so cosy 😺
This SUNDAYS is priceless <--- did i say sunday? 🤣
Don't forget it was released from New Zealand so he probably released it at 12:18 am on Monday August 26 which is roughly 2:18 pm Sunday August 25 your time and around 5:18 AM Sunday August 25 on the west coast of Canada where I am located if I did my math right.
@@retireeelectronics2649 It is only for fun, Scot know that, it is our thing, here and in Patreon 🙃
@@sveinfarstad3897 I was having fun also (-: Where I live my family is scattered over 3 time zones = 3hrs, I just don't pick up the phone and call without looking at the clock first (-: Have a good day
It seems that the beeping is loud to cut through the loud fan noise, and the pump is loud to cover up the beeping ! This unit would be a no-go for me.... I'd have to tame down the volume on the beeper if possible as well as installing a quieter fan.
@@goodun2974 beeping isn’t an issue in reality, I almost never change the temp on it, just pick up the handle and use it. I actually like mine, I did this review quite a while ago and I’m still using it. I did a 2nd video modifying it to reduce the fan noise, and put the power switch on the front, which is where it should be on EVERY product.
HI FROM mICK
where do you find its filter?
Finsri DSO tc3 showing different RDS ON value. I couldn't understand . I calibration 3 times I used 5N65 mos RDS on according to datasheet 2.5 ohms meter shows approximately 0.5 ohms. What must be the problem
Should this be passed over to Pat's channel for testing? All our electric equipment has to be Pat tested 🙂 Well done on the the video length, Just longer than the ad's 😉
@@TheEmbeddedHobbyist yes the company takes care of getting PAT testing done before it is put back into use, I do tests and checks myself too though to fix anything I find before giving it back, better to check it twice !
@@TheDefpom Are you getting paid for fixing these......or just earning Brownie points (both Ok)

Extra parts for free🎉 It would be great if all repairs were that easy.
Thank you!
THANKS!!! I bought it.. but the one with batteries
Thank you for this review; I bought one with your discount code.
Thank you for this video and once again reminding myself never ever BUY Apple product. Over engineered and over priced garbage to the point where Apple themselves abandon their own product without publicly admitting that this series of Mac Pro was nothing but an exercise of ignorance in trying to think the law of physics did not apply to products.
Sir what is the output voltage for amp z623 bcoz mine is already burnt out primary section so I want ed to fix it by myself with alternative power supply output for the amp z623 but you know I could not find the exact output that's why you knows if u can help me by any chance im so happy Sir ❤ thank you&sorry about my english I hope you can understand it 😅😊
What extras do I get if I pay to upgrade? i have a 2007 Peugeot 207cc. Anything useful?
What do you think of FNIRSI DMT-99 is it better than Aneng683 ? I am waiting for a reply .
Hi. Your programme is very good , you do a fair review.They are very helpful .What do you think of the Aneng AN-683 , I am about to buy .Greetings from Poland and I look forward to the next interesting reviews.
By chance just happened to watch this again where at ~7.45 you change from Auto to Manual attenuation which I cannot recommend. When using an external attenuator you should instead leave Auto Attenuation set and adjust the Ref Offset to account for the external attenuation. While set to Auto, the analyzer can better protect itself especially at its most sensitive settings.
I've done the mod for putting the right channel and frequency on the display, if you are interested im happy to help you code that into an esp32 Arduino. Im really surprised to see they redesigned the pcb and kept that crap old pll chip, very disappointing, i was hoping for a serial pll without the masked channels. See my channel for info on the mod i did.
hi Scott , I'm new to electronics and loving the series! One quick question. Is there a possibility that a capacitor could discharge a dangerous voltage or current if you touch both the input and output at the same time. Many thanks
@@hello55125 yes, lower voltages aren’t really a problem, but when you get to higher voltages you can get a nasty shock from one.
@@TheDefpom thanks for the reply
That fan definitely had some time on it! What did you do to modify the DC load to dissipate so much more wattage?
The hardware between the 200W and 300W is the same, so it is a software hack to convert it into the higher model.
@@TheDefpom oh no kidding! that's interesting.
Bought mine in 2011,only Issue is the cable connector in the back who give a bit of interference/crackling noise if i touch it(black RCA connector),and very small click when i open the volume from zero(the rest of volume and bass are without crackling noise like this one.). Don't understand why people saying this is garbage. This played at 100%(full volume and bass) for hours and never died on me.Maybe new build are cheaper,but 2010/2011 models one is rock solid.

To fully load it, you could connect some MR16 24V halogen bulbs in parallel to it. You could buy some 24V 250W bulbs.
You shouldn't have removed that hair that's what was making that particular meter that accurate. 😄
Thanks so much for your in-depth review very thorough and complete to the point. I Should be getting my 179 75th anniversary edition in a few days. Hope it's as accurate as yours.
Well FANcy that. I'd agree with you there.
One fan bearing. Cheap fix for power like that is always nice, congrats. I just got a 25A PSU also. Mine wasn’t given to me but still cheaper than what it was retail. I also had a cheap fix, $0.69 diode and seem to be running good. The fast, cheap and easy fixes are nice once in a while.
watched all three parts of videos .. awesome videos That’s the reason why I picked up on myself but I guess it’s been refurnished Haven’t tried it yet do you think you can do a part 4 showing 100% how to use for beginners, lol resistors and capacitors capacitor and what the scale thing is for ?
I rounded up to 90👍
WD40 may be a good water displacer but it's not a good lubricant - at least for the long term. I'm quite sure you know that but some of your viewers might not.
yep, wd40 dries up in a few days, also that's not good for most plastics and rubbers.
17710uF .26Ohms "seems reasonable". NO!!!! the 2200uF capacitors should probably be less than 50mOhms - each! I'm assuming they are 35V given the 24V output. It's hard to estimate the size but the absolute cheapest 2200uF/35V from Digikey is the EKYC350ELL222ML20S, 16mm dia x 22mm which looks similar size, with a specified ESR of 38mOhms at 100kHz. 8 in parallel would be nearer *5mOhms* than *260mOhms!* Assuming a ripple current of 30% of output current (fairly typical) that would be 7.5Arms. 7.5^2 x .26Ohms = 14.6W 🌡Ouch. I'm guessing the power supply will not be a happy bunny at full load. Never forget the golden rule - *"It's always the Crapacitors"* [EDIT] Since you saw very little ripple voltage at 12A, maybe the ESR measurment wasn't reliable? Or perhaps the designed ripple current in the ouput capacitors is very low, implying a rather large inductor?
I've been soldering since my teenage years... Since it is just the rosin that causes the smoke, is it really that bad for you? Never used a fume fan before... Also know a few people in the repair business that does not use one...
strange 1 that ic had a hole in it
I assume it's 100% up to 50°C. Above 50°C linear derate down to 30% at max of 71°C??
I remember this little cute baby boy of a power supply! 🫠🫠 The large elco's aren't particularly bulged per-se. They're just built like that. Like ass, with a few bulges and a crack in the center. Fans getting faster and slower like that generally/often have issues with gunked up grease/oil in the bearings' races or bearing sleeves. The heat of running liquifies it more so they get faster as they run, but dust and dirt in the grease can then also redistribute and cause it to intermittently experience more friction. This one looks like a ball bearing one, judging from the large fan motor hub, even without needing to open it up. That's how I can tell. :) When oiling bearings in fans, please don't use WD40 as a lubricant! It works wonders for flushing out old grease as it's mostly solvent, but when it evaporates it has no more lubricating properties. Use sewing machine or light machine oil (or, if you must, 5W-30 or 10W-30 oil)!
I have seen this video... 😂
@@sveinfarstad3897 well, sort of.
Yep, was a live stream. Now the proud owner of this PSU. Thanks Defpom ! 👏
@@tautech8196 Patreon for 4 days ago 🤣
Good find. Over the years have seen tracks and vias disappeared underneath conformal coating due to corrosion. Bad PCB manufacturing process.
Yes - screws nice and tight but NOT OVERTIGHT where they are going into tapped holes in the aluminium frame. If you have gorilla arms it's too easy to strip the thread! (and that will often not be easy to fix).
Why can't you just remove the blocks at the top of the lead screws with the x gantry set at the bottom? There should be enough safe flex in the lead screws to remove them, insert the pulleys and fit the belt. That's how the block was originally fitted to the single lead screw on first assembly.
Sometimes is not possible to understand your English...
You can turn on closed captioning.
Thanks Mate good Video.. I bought one of these a couple of years ago.. just found it again... was in the boot of my car.. never used it but I will now after seeing your video...
Nice one!
Hi! I'm going to try this but I see four red connections? I need the video signal, the reverse and what else? Thanks for a good video!
