B1 Buffer Preamp

[brutepuppy]

That's GREAT!! Can we get a wiki for those of us who want the board and sign up? Is there someone here who has the expertise to post a new wiki (if that would be appropiate at this point)??

 

[si_jopie0382]

WOW, Thanks Nelson

I would like to join for 1 set

 

[noelectrix]

so this will be one of the last perfboards even if not working

 

[jacco vermeulen]

Where oh where do you guys get those lovely FET heads ?
Stefan at the Deutsche Anal-F has them as well.

 

[noelectrix]

shrink shrink! and additional glue, in case it gets too warm.

 

[Professor smith]

where can the circuit boards be obtained and how much will they be?

Passdiy.com Store

where can the circuit boards be obtained and how much will they be?

plus shipping and fees from financial transaction agents- NP

Passdiy.com has a store. When you see the PCB or part in the store, you'll be able to purchase from a Paypal cart. That's what they used for the Pearl Ono PCB. Assuming it will be the same for the B1 and others.

[Professor smith]

buy them at the cost of our vendor's invoice divided by the number of boards plus shipping and fees from financial transaction
agents.

That is kind of you, however, it appears that you are willing to give alot away for free which is interesting given that most people would try to maximise their profits. Out of curiosity why is it that you choose not to focus on this aspect of maximising profit and instead give things away for free?

Of course nobody is complaining.

If you need to ask, you wouldn't understand

...Tomorrow I'll admire them, and ... then you can either
make your own off the gerber files or buy them at the cost...

Nelson, you truly are a scholar AND a gentleman!

Hi gents,

apart from some cosmetics my buffer amp is finished now. Last night I did some testing and found I like the "sound" very much. The high quality of this buffer will urge you to find out the "weakest link" in your audio chain, it won`t be the buffer-amp. At a first glance it sounds very transparent, just as if it isn`t there.
Attached my "form follows function approach" without the covers mounted. Tanks to Mr. Pass for sharing his brilliant ideas.
I am already unpatient about what the B3 will be like.
Regards, Jürgen

Nice one. Is it 4 channel? buffering some crossover? Single supply version right? Output cap values?

 

[pozo1992]

Hi there,

yes, these are 4 channels, more like a B2. I am using the second pair of buffers together with the second output for two purposes:
-buffered output without attenuation for a tape deck
-buffered output with attenuation for sub applications
The switch on the right side serves this purpose.
The output caps are 10uF MKT.

Here's a picture of both sides.

How about personally autographed boards in exchange for a donation to a charity of your choice?

BAF is too far for me, so unfortunately, I won't get a chance to meet 'The One and Only' this year.

Like perhaps www.diyaudio.com ?

I know that Mr.Pass is partial to....................

 

[Professor smith]

Here's a picture of both sides.

Why are the tracks so thin and the traces of the holes so thin?

They look fragile.

And why did you choose to do double sided?

 

[MikeW]

I know that Mr.Pass is partial to....................

That's the best you could do? You have better bottles than that.

 

[troystg]

Like perhaps www.diyaudio.com ?

Yes, EXACTLY.

How much do we need to donate to get a signed set?


Oh and AGAIN thanks for all you do for us mere mortals...
