Hi There is some videos in youtube showing dell or hp psu hot plugs convert to bench power suply. They could run the psu hot plugs by connecting some pins but they just could run them to take a small curent not the maximum curent. Could you please tell me how to run my "hp 2450w hstns-pr16 platinum hot plug" and "hp 2650w hstns-pr42 platinum hot plug" into a bench power suply to take the maximum curent and power? Kind regards Kevin

please make a tutorial that how to connect to serial interface and send serial data to computer . thanks!

Thank you for this video! I needed to know where the IR sensor was located and I couldn't see through the plastic to locate it, not even with a really bright light. I need to block it with tape so it can't receive errant signals from another device's remote.

I just wonder where are you located??? To see if could repair my speaker Joel flip 3 asap

Mr. I have the HT-R550, its displays turns off after a few minutes. I am not a certified technician, nevertheless I found out when the Cirrus Logic IC CS42518-CQZ got heat the displays fails... Applying circuit board cleaner the propelent cools it down and the display turns back on AGAIN for a moment... At this point I have the circuit diagrams and I already ordered a replacement chip JUST IN CASE the IC is damaged. I suspect it is not and MAYBE a surrounding capacitor is. I'll try to check the capacitors... in the meantime, I'll appreciate any comment regarding this issue. Greetings, from MX Rodrigo

That cable stripper looks next level shit !!! Nice.

Brilliant use of that flux pen!did any of the silicon grease go over the wiper or track?

I just bought one of these and it works great, but i want to preserve it. Would you happen to have a list of all the caps you replaced (new ones)?

What's grease to you recommend using?

To open the shell you must remove the 2 rubber wall hang plugs and the 2 raised stand offs (feet) to expose the 4 screws. Use your fingernails to pry open both sides (left & right short ends) then pry the bottom apart (thinner edge opposite of the antennas). If you want to remove the board there are 2 screws (near lights and wan port) and 2 antenna mounts to remove.

Hola..desde celaya GTO.. México..es normal que los receivers onkio..se calienten en encendido.. gracias..IMG

There’s no isolation between input and output is there. Not that there’s a 240 volt input.

when i turn mine on the battery voltage reads 7.1v even though its a new battery . dont know if this makes a difference , and a 470uf cap reads 66470uf ??? any ideas why

Hello, is it possible to connect this tester to a PC?

Ive juat gotta say I would not ever pump that cleaner that hard. High risk.

really really nice. next time try to put some reverb on that 'fuull bridge rectifieerr'

Do you know any replacements for the rotary switches?

Thanks from Brasil!!

Thank you so much for this!

I just relapsed the battery in the same machine with "Varta 2/V150H" that is a drop in replacement that is still in stock at RS Components

i actually have an tds 644b with 684 board(the original board has been take a shower on capsfluid and drop the magic smoke) i change it his board and the caps in new boar, but still not working (only turn on and off every second) maybe need to check power supply too

ola !! tudo bem? uma pergunta, voce consegue detectar o efeito early? grato um abraço!

Would you be able to share what connectors are you using (mfg/series) and what particular crimper? I’ve been thinking about getting Japanese crimpers for some common contacts.

It is possible to buy bulk white toner and fill up one’s own old cartridge. For front panels I’ve replaced the Y cartridge with white, getting CMWK capability. The cartridges can be reordered to get good coverage of white on black etc. It just needs some small changes to the postscript file sent to the printer. Why postscript? So you can fully control what’s drawn with what color. Otherwise the Adobe+Windows color management messes it up.

Free alternatives: For drawing - Inkscape. For public mechanical cad (2D and 3D) - OnShape.

Okay fint nok. Alle kan skille en computer ad og sætte sin finger på hardwaren og sige en hel masse kloge ord om det.

Hi mate! thanks for the video! Just a question, where did you get the PSU schematic? Im struggling for a while to find PSU schematic for TDS380 and 420A. Gday

J'adore, je suis pas au niveau pour en avoir besoin maintenant. Ce que j'aime le plus c'est la somme de travail et les progrès accessibles aux amateurs, fini les boites en pcb, les circuits en l'air, etc. Very professional work. I have seen many power meter on ebay without sensor, so at this time i play with ad8307 and analog voltmeter. Thank for sharing your knowledge

hi, can you replace it with a usb-c instead?

I took apart mine and looks like now they put in there a controller in a SOP package, SMD leds and passives. No power LED. But solder joints are very bad, there is barely any solder, you can see bare copper pads. Also this thing is USB1.1! Max rate 12 Mbit/s. Shameful!

I actually built a Super80 many years ago. Eventually upgraded to CPC464 in '85.... The only item I have of that machine, is the manual... I still use it... Of course, the Amstrad, is now emulated.... and I still use it now and then when I feel nostalgic... Good memories... Thanks for the video!!

You seem to skip over the amplitude settings. In fact, you go from shoving a board back in the machine straight to showing measurements without showing us what you did to get there. The % distortion is variable with amplitude so are you measuring distortion at 3V?... because no one has a clue since you didn't show any of that.

Nice work guys, really thorough teardown.

Wow and here it thought it was axreal repair

What software did you use to design the labels?

Great tutorial!! My edge brush stopped working. I took it apart and cleaned out some cat hair that had worked into the gears, and it's working great. Thanx!!

Can you show us how you make these - eg how you get the measurements so accurate in the design software

I really want to know where you get your flux from ?

How is about it schematic diagram ?

So much nicotine on that I'm assuming you got it at an estate sale 😂😂😂

thanks for the video, but I need replacement side brush gears. The screw broke off so I need to relace the gear that holds the screw for the side brush.. Do you know if they sell replacement parts ?

Hi, i want to buy this unit to replace bad LED's on TV backlight LED strips. Do you still have the unit? If so, is it still working good? Are you still satisfied with it? Hope to hear from you soon. Many thanks in advance

This wasnt genuine

Keep an eye out for an HP 6515A power supply - 0~1500 Vdc @ 5 mA - great for reforming and leakage testing of higher voltage electrolytics. I use mine for this regularly - use bench meters to monitor voltage & current, set the PS output to the cap's rated voltage and let it rip.

Great teardown, big thanks for it.

This knob is original 🙈

These are really nice . There are a lot of TG501A,SC503,PG506A units out there with the newer red Lens that would benefit from this service if you had the time to make up the files for them .I certainly would invest in a set of the 3 .for my set . I'm presently looking for a SG504 and will get one for it two ...........Well done!................. these cosmetic projects are just what is needed as there are loads of working but crap looking 500/5000 modules out there .i wonder would PCWAY be able to reproduce the silk screen fronts as well ?PS I just did a couple of TM503 facelifts with your boards. Had a tight squeeze on the Nichicon 4700/63/105 caps I put in leu of the no longer available ones in your BOM. Worked out very well . I dont need the pinouts at the top so just insulated the area with capton below the wider caps.Thanks.

The inside of mine does not look like that and I bought the same model

My ruumba is only 2 months old but my house is all Hardwood with 2 kids 😂......ty! The brush has hair in it lol
