Re: Soldering Iron tip question?
Question: Tinning the iron.
I've never soldered (properly at least) until after watching a few video tutorials on YouTube and doing some basic research into the skill. They all pretty much say you should tin your iron.
Well, I have two irons. A [URL=http://www.frys.com/product/248964]Hakko[/URL] [B]40W[/B], and an [URL=http://www.amazon.com/ECG-J-060-Watt-Soldering-Iron/dp/B0002GLZN8]ECG[/URL] [B]60W[/B] with Qualitek Rosin Core Wire Solder, 60/40 (.032"). Regardless of what iron I use, I can't seem to get them...

Re: YACQ - Yet Another Capacitor Question
I ran into a similar problem with my PSU (waiting on other parts to come in the mail). There were only three caps that vented. Those happen to be the only three that were 2200μF at 6.3v 8mm x 25mm. I sent an e-mail to sales/support @ badcaps.com looking for replacements. I was informed that it was an unusual spec and that it must be 10mm x 25mm. But no, my measurements were correct. But I digress...
The point is, I was able to get 10mm diameter caps to fit. It was a tight fit, but doable. Had it not gone my way, I would...Leave a comment:

Re: A Reminder about PSU Dangers and Liabilities
Thanks for the update Keri. Reading your post was quite a reality check. No doubt PSU's are some serious devices. In fact, I'm attempting to repair one of my own (for personal use).
I'm going to mark my unit as [B]"BAD! Do not use"[/B] should it ever end up in the trash. I sure would hate for some poor SOB to use and/or mess with it 3rd hand.
Given the economic condition everyone is going through, you can bet those litigious bastards (lawyers) are hungry for blood and on the...Leave a comment:

Re: Dead PSU - Zalman ZM600-HP
Thanks for the Info.
My only concern however is that part is rated for 560uF while my original CapXon was rated for 390uF. Shouldn't I replace it with part [URL=http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P14093-ND]EET-HC2S391KA[/URL] instead, or does it not matter?Re: Dead PSU - Zalman ZM600-HP

Re: Dead PSU - Zalman ZM600-HP
The original fuse was ceramic. But I'm not sure if it was a fast-blow or slow-blow fuse. Is there any way to tell? If not, what do you guys recommend as standard for a PSU such as this?
Thanks.Leave a comment:

Re: Dead PSU - Zalman ZM600-HP
Well, there's only one of the large caps. I'm guessing it's the AC input cap. You can see it in the photos taken [URL=http://www.rojakpot.com/showarticle.aspx?artno=351&pgno=6]here[/URL] at rojakpot's website. In fact, the same ones shown there are what's inside my PSU.
And yes, that cap is slightly domed. I double checked. It's not just the plastic stuff. It's a CapXon 390uF at 420v. LP series. Vent 85°C.
Should I bother replacing it too?Re: Dead PSU - Zalman ZM600-HP

Re: Dead PSU - Zalman ZM600-HP
Oh, I *want* to fix it! If it wasn't for the crap caps, this would be the best PSU. Period! It's uber quite (in fact, it doesn't make a sound) and provides all the juice my workstation needs.
Slight problem however. I really want to know how a 10 amp fuse popped?? I'm in agreement with you. I think those caps vented some time ago prior to the fuse going out. The residue was not wet, but dry and crusted. I suppose I could recap it for a cost of about $10 (includes S&H) and replace the fuse. But if it pops again... the journey to resolution...Leave a comment:

Thanks for the reply
Unfortunately, I couldn't locate a MOV on this unit after doing some searching online. In fact, according to this [URL=http://www.hardwaresecrets.com/article/402/4]article[/URL], my PSU was never built with a MOV. Is that possible?
I really wanted to get this PSU up and running as a spare for when I might need it. Too bad it's more trouble than it's worth.
If you have any other suggestions, I'm all ears.Re: Dead PSU - Zalman ZM600-HP

Dead PSU - Zalman ZM600-HP
Hello everyone.
I'll try and keep it short and simple. One night, I came home after a nasty storm only to find my PC turned off. Everything else checked out ok. My monitor, and external speaker system had power. It was just my PC that wouldn't power up. All three were connected to the same surge strip.
After further inspection, I isolated the issue to my Zalman PSU (Model: ZM600-HP) not getting any power. At this point, I noticed that the fuse was blown as I wasn't getting any continuity through it with my volt meter. Secondly, 2 out of 3 CapXon 2200uf & 6.3v...
