Re: Speakers in Series or Parallel?
If it's rated to drive down to 2Ω loads, parallel will be the best option (it is highly unlikely that the paradigms are under 4Ω). The SS20 looks like it is up to the job for you.

Re: Hakko 808-5 desolder gun
might be wise to invest in an ESD safe one. I once read over at diyaudio that the non-ESD safe ones can blow up mosfet gates...not sure if there's any truth to it tho.Leave a comment:

Re: Bypassing high frequency currents successfully
This is really nothing new, its quite frequently used even on low-freq. (60Hz) board designs. It's somewhat analogous to star grounding (directing the currents & such)..

Re: Hakko 808-5 desolder gun
Just wait for one used on ebay. I bought a hakko 470b w/ a few parts missing for $100, spent a few bucks and got it running.

Re: Asus A8N-SLI-SE No Post, Need Recap or not?
My A8N-SLI has been running flawlessly for nearly 4 years, I don't think it is the caps that are your problem. How have you determined that the mobo is the problem?Leave a comment:

Is there anything wrong with the knocked off cap (dented/smashed/leads damaged)? If not, just reuse it.Leave a comment:

Re: Sony amp "protect" issue
Sounds like a bad solder joint - check any transistors attached to smaller heatsinks.

Re: Sony amp "protect" issue
Some older STK chips are just notoriously unreliable - you'll find no shortage of projection TVs with dead STK392-110's. My dad's STR-GX900ES reciever had a channel go out one day - intermittent STK350-130A of course. Ended up just using a good chip from the center channel and all has been well for years.

Re: That's where the power gets lost,” Mr. Shamim said
Really, this is not as surprising as it appears. Transmitting rf power efficiently is not at all similar to how we transmit dc or low-frequency ac.

RF signals do, after all, propagate in air and other dielectrics (clearly not electrically conductive mediums).Re: That's where the power gets lost... is not at all...Leave a comment:

Re: Dell XPS 210 with bad caps!
Other members will tell you, KZGs don't like heat and can die, even though they're 'good' caps in every other way. Having a tiny pc case and using them with a hot chip won't do the KZGs any favors, it's a good idea to replace all of them used in the VRM low side, high side is probably fine (low ripple) - if applicable.Leave a comment:

Re: PSU badcaps!
For a few minutes, probably nothing permanent. Anything longer is debatable and not worth trying. Electrolyte leaking won't look like a cap dipped in honey, electrolyte isn't too viscous and usually evaporates, leaving a residue.Leave a comment:

Re: 10v 3300uf substitute
6.3V will work fine in a psu, the same is usually true for mobos too. The only rails that exist in a psu are >10V or <6.3V, so replacing the 10 with a 6.3 is fine if it's a rail capacitor. Teapo is probably the single 'bad' brand of cap that is generally OK to leave in a psu (assuming they aren't bad already), as they seem to survive the lower switching frequency, as opposed to much higher frequency noise on mobos.Last edited by PM650; 01-09-2009, 09:25 AM.Leave a comment:

Re: Can new caps have slightly bulging tops?
Frankly, I (myself) wouldn't bother installing any caps at all that were questionable in my mind. This type of thing could come around again in the future and bite you, better to do it right once and forget about it. I recently redid a psu that had completely vented caps...from just sitting around in my room for a few years (although they were Jun Fu's...). The caps didn't all of a sudden decide to completely bloat one day, it was a gradual process, one that the caps you got cheap may already be going through, potentially due to improper...Leave a comment:

Re: LP NF2 Ultra B CAP PICS
Yes mixed branding is quite frequent. My Asus A8N-SLI premium has rubycon, chemi-con and panasonic scattered over it. An MSI radeon 9800pro I have also has rubycon, chemi-con, panasonic and fujitsu on it...
Replacements are up to you, they don't have to be the same brand, but I just use all rubycon since its easiest/cheaper for me. It is a good idea to use the same brand/series in a group of capacitors, like the VRM for vid card or mobo.Leave a comment:

Re: LP NF2 Ultra B CAP PICS
Teapo are usually OK in a psu (low frequency ripple), but they will eventually vent if they're on a mobo. I just did an Abit KR7A a month ago, full of teapo, several were venting, but not horribly (board in use since ~2001).
Those gold/black caps look like Ost on the mobo, I just replaced all of the Ost's on my Asus A7N8X Deluxe (same age NF2 mobo as the DFI) and it cured some stability problems, even though they weren't used for the VRM and none were vented.
The light-brown caps in the first few pics with the 'Y' vent are...Last edited by PM650; 01-02-2009, 03:06 AM.Leave a comment:

Re: Socket 478 pins
M6 is #8 address line, certainly not redundant, unfortunately.
"A[35:3]# (Address) define a 236-byte physical memory address space. In subphase
1 of the address phase, these pins transmit the address of a transaction.
In sub-phase 2, these pins transmit transaction type information. These signals
must connect the appropriate pins of all agents on the Pentium 4 processor in
the 478-pin package system bus."Leave a comment:
