F5 power amplifier

[tinitus]

those boards are pirate stuff

look up the spec sheets, and study transistor orientation carefully, and ofcourse F5 manual

in a week or two you will be able to build it on some of those point whole proto boards

not very difficult, and maybe even much better


btw, I think all kinds of power supply boards sucks

as a minimum one should learn how to build and wire a simple power supply

then it might make sense to use boards

well, thats just my personal opinion

Hey you don't miss much

sadly in some parts of the world its all at the time, we new was available,

But the world wide publicity they give to Pass Labs / First Watt, I would think Mr Pass makes up for that way, and the stamp "PASS F5" on them dose just that.
What you lose on the swings you pick up on the roundabout.

well, be grateful that Nelson Pass is such a nice man, or he would have closed the box a long time ago
Im pretty sure he hates to see his name on those boards

But you do make a point about fault.

To Franz:
On my version of your board my "Q1" is in the complete opposite direction to yours, and mine sounds brilliant, even tube lovers with McIntosh valve gear love it.

Franz see page 779 for more details and juma's comment on that page. I'm to scared to try it the way on your board in case i mess up the detailed sound.

I do nicely without their help. Pirated trademarks is my biggest
problem - they have difficulty selling these without my name on
them.

Sorry, Your right It is your name, they are selling on,
And although people like me have got involved the wrong way round at the time, I didn't know of any other options, But with out these forums there market would dry up as its the forum that irons out "there" faults and gives support.

From forum readers who know very little about these things its a million dollar support channel they are not paying for, and if there was anything I could do for someone in your position to show my appreciation I wouldn't hesitate, Because of my learning difficulty which have always stopped me going forward, You cant imagine how much this whole forum (which wouldn't work with out your support and input) means to me and those like me.

So A big thank you Mr Pass , and my words stand corrected sorry.

AWC,
Just to clear up another apparent misunderstanding, the forum is NOT here to help iron out the faults of the pirated boards and provide support to people who buy them.

What the forum does do is enable access to APPROVED Group Buys for boards and, through the diyAudio community, provide support to those who choose this legitimate path.

So there are other, better options!

Currently approved F5 boards are available from cviller and Peter Daniel on diyAudio. In both cases they provide excellent support. Here's the two links:

Ok so some good has came out of this unintentional thread hijacking,
With Mr Pass and jimbo51 along with tinitus comments.

Everyone will now know beyond a shadow of a doubt under no circumstances buy Chinese made boards or come to this forum seeking advice if you have,
whether your aware of the other options mentioned by jimbo51 or not.

I apologize for taking up your time and have already apologized to Mr Pass but just be beyond a shadow of a doubt, I'm sorry again Mr Pass for using Chinese made boards and taking up your time, and thanks again for making it possible to hear the quality sound im hearing,
no other manufacture would have bothered let alone constantly go that extra mile.
I will now remove myself from DIY forums cause I have a Chinese made board.
awc.

[tinitus]

awc, I hope you will sleep on it and think about, that ist a fair asking that Nelson doesnt have to look at those boards when he comes here

and that they are not "advertised" here as well

enough is enough

no more of this, lets move on please
