Re: Where to buy decent 'mini' probes ?
This multimeter is a generic, I have one labelled BECKMAN INDUSTRIAL and I've seen others with different 'manufacturers'. It's a good wee meter!
Also, those probes are nice and slim, but the actual tips are annoyingly large and easy to short when checking stuff with smaller spacing.

Re: Channel Well DSI250P
Quick update: it's [B]dead[/B].
PC would only 'blip' on for a half second today. Opened PSU and all looks well. Removed every SAMXON cap and replaced with some Rubycons I had lying around. PSU now 'starts', actually it starts the moment it's plugged in, which ain't right.
Put PSU tester on it and the -12v line is perfect the rest are high and low. 12v @ 7v and 5v at 6.15! 3.3 dials up 1.4v.
Looking around the web I see the consensus is these PSU's are total dogs**t. Not going to cry for too long over this one...Leave a comment:

Re: replace OEM bios with manufacturer bios on intel mobo
You could also use the Award of Phoenix tools to enable the features that are missing in your BIOS. They will all be there, just disabled in the ROM image.
I recently added SATA and RAID to a WYSE dumb terminal this way: makes a nice wee NAS box!

Re: people are sheep when it comes to beats audio!
The 'engineering' part was also sarcasm. Dr Dre lent his name to a brand for money: that's his contribution, he sold out to punt a product.
You should recalibrate your sarcasm detector, as my last post was set to 'blatant'.

Re: people are sheep when it comes to beats audio!
Audiophool?
The RHA's cost me $20 (15 British Pounds) and sound far better than BEATZ crap.
If you read and [U]comprehend[/U] you'll see I'm slating the Beatz, which are nasty made in China hardware marketed by a sell out (Dr Dre). Google 'sarcasm' for help with that one, but the clue is where I say that Dr Dre is a scientist and imply that Justin Bieber is somehow important to music.
I've never tried Sentry, but I'm willing to bet they sound at least as good as BEATZ products...Leave a comment:

Re: people are sheep when it comes to beats audio!
Listen you guys, well known and widely respected audio scientist Dr Dre worked in conjunction with Justin Beiber to painstakingly engineer every aspect of the new BEATZ hardware. They are in short, design excellence.
I'll stick to my RHA's. A fifth the price of that sh!t and sound 100 times better....Leave a comment:

Re: Got this Hard drive dock in a trade.
I have the exact model you do. It's rubbish. Totally unreliable, good if you want to wipe a hard disk quickly because every second write it lays down some garbage to the disk.
YMMV, best of luck!

Re: which one to use...
Because I switched it 'off' and in so disabling the feature it shouldn't occur, ever.
Yes, that's why I have the most up to date BIOS installed... My thinking is that they just stopped working on these BIOS updates as that CPU came out so there's some incompatibility they will never ever address. Ah well!

Re: which one to use...
At BIOS level and in POST? I'd have thought SpeedStep would be off at that point and the cpu running at max clock. The board supports SpeedStep and CPU-Z reports it's enabled and working OK from within the OS.

Re: which one to use...
Hey, my GigaByte G33 does exactly the same thing with my E6600... I dunno why, but it always sets the multiplier to 6 when it should be 10. Something about newer chips not playing nice with older boards, I'm not sure?
That system also writes errors into the event log sometimes about APM having a firmware issue, so I guess there's a nice wee CPU microcode clash there somewhere.

Re: Swollen SANYO Caps on G33-SL2?
Ah, ok, that's great news!
The feeder caps in the PSU are Teapo (yuck) 3300uf capacitors, but they are all in good condition. The PSU is a HEC Zephyr 80+. A look inside reveals everything looks splendid and no large amounts of dust either.
I reckon I don't have anything to worry about with these caps then. Maybe the first example was a one off and the ones that look more contoured are actually the norm.
Thanks guys!

Swollen SANYO Caps on G33-SL2?
Hi guys!
I need an opinion on something real quick!
Here's an example of a new (six month old) Sanyo cap;
This is on another device (a dumb terminal) which has lead a charmed life, hardly ever switched on. Looking at the cap the vent is nice and flat with good sharp edges. It looks 'healthy' to me.
And here are the others on my Gigabyte board, which for the last three years has been on almost 24/7:
Notice the 'softening' of the top? Looks a wee bit bulged and there isn't a sharp edge or clean... -
Re: Beckman Industrial 320B
You could try soldering in a larger piezo beeper - failing that a transistor (one side to the [I]battery +[/I] the other the [I]beeper output[/I] driving something a bit larger could be an idea?
Could go as loud as a smoke alarm sounder if you wanted with that one!

Re: It's not just electrolytics that can go bad...
Yep, two dehumidifiers and an air conditioner I had both failed to produce enough power to click the relay over; with the problem being a failed 1uf cap on the mains!
Last thing I suspected, but after a day of replacing transistors and resistors I got there in the end!

Re: Channel Well DSI250P
Hmmm, yeah that makes sense. Once I tear this PSU apart I'll try and find specs for the caps it currently has and compare with the new ones going in. I'll post findings of course.
That said, once I've recapped this 'un I reckon a few weeks of testing could be the way to go before I consider it fully stable enough to load on all my porn, uhm, I mean [I]important business documents[/I] on!
Wish I had a load tester / ripple meter.

Re: Channel Well DSI250P
Well, the greater the ripple current rating the better, no? :-/
Yeah, these were the best option for 8mm caps I could find. I think a 1cm cap might JUST fit in there, but it's going to look a bit like a bunch of mushrooms standing proud from the board, which I don't like the looks of!

Re: Channel Well DSI250P
Yep, I spent MONTHS recapping lots of things with those shh!ty green Samxons in them; it's why I don't trust the brand as a whole now. I gather they have improved greatly, but with plenty of other options for similar money, I shant be testing the theory!
Oh? Tell me about that?
I have Panasonic FR's that I can get very cheaply. Here's an example:

Channel Well DSI250P
Hello my friends!
I have just started using this:
[url]http://www.xbitlabs.com/articles/cases/display/mini-itx-cases-roundup_9.html[/url]
The Channel Well PSU, it's in a FoxConn Mini ITX bare-bones. Opening it up and having a poke around it looks to be a fairly well made PSU. The caps are SAMXON though, a brand I do not trust. For this reason I intend to recap with some nice Panasonics - and I shall also up the 1000uf secondary output caps to 1500uf.
Also, I notice there is a primary input filtering coil, but also space on the board for... -
Re: Speaker as noise detctor.
You might be able to train a dog to detect the high frequencies... Lotta' work and expense though when a scope could do it.
