Stumped this weird G4 power supply problem

Re: Stumped this weird G4 power supply problem

Please post what you are ordering for which cap# *before* you place the order.
I'd appreciate the chance to review them.

Something like this: C16,19 - Rubycon ZL

In these units, I have used Panasonic FM & FC series, Nichicon HZ & PW, and United Chemi-con LXY. Everything from 0.47 - 47uF is fine. Also the 470uF on the fan board is not a problem. That takes care of 17. The other 11 are the problem children.

Re: Stumped this weird G4 power supply problem

I can actually get these caps out quite easy, the pain in them is cutting away that glue. My problem has been sourcing the parts. I went to 4 places and bought from 2 and still didn't get them all and now it turns out you guys are saying they suck.

I decided I'll go with a combination of the rubycon and nippon

For starters this would be the complete set for ACBEL minus the big ****ers

0.47uf (4pc)
4.7uf 50v
10uf 50v (I didn't change it)
47uf 50v (I didn't change it)
47uf 25v
100uf 25v
220uf 25v
470uf 35v
680uf 35v
1000 10V 8mm x 16mm (2pc)
2200 6.3v (2pc)
2200 16v
2700 6.3v (I didn't change it)
3300 10v

I'll edit them later with sizes and the C numbers

Re: Stumped this weird G4 power supply problem

I hear you about sourcing. In addition, we Canadians pay what I consider a non reasonable ship/handling vs the USA for companies like digikey and mouser.

In USA, it is about $2.50 USD for s/h. In Canada, it is 8 CDN + GST + HST for s/h.

You should be able to get all your caps at either digikey or mouser Canadian websites.

Don't get me started on this. I used to sell things online. In the US they pay about $60 to ship a 10kg box to Europe. Canada post charges $200 for the same package. We have the most corrupt postal system and I never could figure why the price is 3x higher than our neighbors.

customs tax, perhaps?

germany to USA for a 10kb box via DHL is 45eur / 56.90US$ / 58.74 CAD
to canada it's exactly the same..

edit.. uhm.. 10kg .. not kb .. lol

Re: Stumped this weird G4 power supply problem

Digikey and Mouser both have "Canadian" websites as prices show up in Canadian dollars. So I'm assuming that parts actually come from Canada and are not subject to customs tax.

So that can't justify the almost $6 difference in s/h.

customs tax, perhaps?

Re: Stumped this weird G4 power supply problem

doesnt really say much.
the german digikey site also shows everything in euros .. yet the parts actually come from the USA which makes the whole site pointless for "normal" people unless you buy tons of crap there (free shipping above 65eur/82.20US$ value of goods .. otherwise at least 18eur/23US$ shipping)

if the stuff actually came from somewhere in germany, shipping costs would be usually somewhere around 5eur/6.32 US$ .. incl. insurance + tracking..)

You missed the point, we are talking about US shipping intl vs Canadian shipping intl..

For example a man in niagara falls, NY can ship to a 10kb box to germany for $50 but someone from niagara falls, ONT would pay $170. Canadian shipping is 200-400% times US rates.

Re: Stumped this weird G4 power supply problem

didnt miss the point.. just wanted to point out that there's no difference from the other direction... so something's fishy over there :P

edit: lol same mistake... 10 kilobyte box

Re: Stumped this weird G4 power supply problem

No not taxes. We just have a shit postal system. We pay tax when ordering things but its the same rate as in store.

yes generally the price is the same going from us to canada or canada to us, the price is within a few cents as the distance is the same. but we have no competition when it comes to shipping intl. canada post sets the rate and the other few companies follow it to within a few dollars. it still doesn't account for the main point. That is shipping 8000km from new york vs 8000km from ontario is 3 x the cost. go ahead and get a quote yourself.

so the fujicon is a no-no....

Re: Stumped this weird G4 power supply problem

translated he just says that those other light blue caps are Jun Fu, and the other black cap on the right is a C(r)apXon..



the do in fact seem to be related to Licon (.com.hk) ... so the "quality" is prolly equally crappy as if it was related to Jun Fu or CrapXon..

edit: can't hotlink to the web.fc2.com webspace.. reuploaded the pic to my webspace instead..

Re: Stumped this weird G4 power supply problem

Why do you keep screwing around with questionable caps? I just don't understand.

If you read anything on this site, you have to understand the problems with them.

WTH is "Panasonic Ultra low ESR" ??? That sounds like a scam too.

[JOHNBOY]

Re: Stumped this weird G4 power supply problem

Well I didn't say I was going to buy those exact ones. That was just what I had in mind. I was more worried about the ELNA brand.
