Re: I can be an idiot sometimes
Did you mean "iron curtain"?
Nowhere is heaven, of course. Europe is more expensive than US, especially eastern part, but we have lower wages here.
The real problem is that we have no surplus, nothing ...

Re: Power Supply
12V will prevent the transmitter to obtain full power. The power supply can be modified, if you know how to, but any switching supply will supply noise.
The best solution is one biiiig transformer, prefer a toroidal one.Leave a comment:

Re: best cheap/free scores 1.1
I've got a WRT54G v7 (does not support dd-wrt) for around $5 here as defective. In fact, the power supply was bad, the router was working just fine.Leave a comment:

Re: ATX power supply not made in China
My search about Zalman units revealed that they outsource to China-based OEM's.Leave a comment:

Re: recommend ESR meter, Multimeter, hot air rework station
It depends mostly on where you live.
About multimeters: Fluke second-hand are very good tools.
About ESR meter: Blue ESR meter or Peak ones are good, but quite expensive if you don't live (read: payd well) in wester Europe or USA.
As for hot air rework station, if you specify professional, be ready to pay a premium price. Weller, Ersa, Hakko are very good tools at a price.Leave a comment:

Re: Capacitors for SPS
Sorry, forgot to mention that the capacity of filtering caps also depend on the frequency (on which the switchers are working).
So, it's not too easy to tell a value without knowing some information.
Usually, for 10A a value of 1000uF should be fine with most of the modern switching PS.
And because a PC PS used a 3300uF filtering cap for 30A, I suppose that for 20A you should be fine with a 2200uF.Leave a comment:

Re: ATX power supply not made in China
Unfortunatelly I can't tell you just that the electronics industry is a heavy polluter, so it still exists where law about pollution are loose.
Hardly any electronics are made outside Asia, and if you exclude China, South Koreea is the second electronics producer, if that can be a hint. I'm not sure that Zalman, which is a koreean company, actually make something in Koreea.Leave a comment:

Re: I can be an idiot sometimes
Jack, me and Th3_uN1Qu3 are living in a east-european ex-comunist country.
In the former comunism times Lamba and HP were ... let's say "enemy".
Afther the fall of comunism, everything made here was tought to be bad and scrapped right away in the early 90's. Afther that they found out that they don't have enough money to buy modern ones.
And ... sad end of story.Leave a comment:

Re: 2 sec to off, 22" LG Flatron, W2252QT
No, but you can trace the circuit and identify which one goes to which voltage easily.
Usually the higher voltage caps are feeding the invertor, and the smaller ones the logic board.
You can be sure that you can find another caps afther the filtering caps on the rail to the logic board.Leave a comment:

Re: Using an ESR Meter (and Reference Chart)
ESR is not the same for a capacity at different voltages.Leave a comment:

Re: Has anyone of you guys seen these?
Still got a lot of them in my boxes, from old tube tv's. They were quite common in communist countries, made locally, and very reliable.
Altough the oldest caps I have are from a National TV (now Panasonic) made in 1960's. And they are still within tollerance!Leave a comment:

Re: I need Dell GX60, GX260, and GX280 advise...
Sure, PCBONEZ, you are right. But if it's only one, you can test the ESR on-circuit.
Altough, even there's only one cap, one cannot test capacity in-circuit anyway.Leave a comment:

Re: Bother with sound card?
You will get some better quality with high-end sound cards like M-audio, but that depends on your budget.Leave a comment:

Re: New-old stock capacitors
I have many old caps, one of them dating before 90's which are ok. They were not used, just sat in a box.
But also had several ones damaged also sitting.
You may never know.Leave a comment:

Re: I need Dell GX60, GX260, and GX280 advise...
You cannot test the capacity in-circuit, just the ESR.
Remove the solder around one leg of the capacitor, make sure that it will not touch the PCB and then measure it. That's the best you can do.Leave a comment:

Re: Capacitors for SPS
A power supply uses many caps in different roles. A cap used for filtering is not the same as a startup cap for example. Or a cap filtering 20amps is not the same as a cap filtering 500miliamps.
Which role you are talking about?Leave a comment:
