F5 power amplifier

[Skorpio]

I got my matched JFETs (2SK170BL and 2SJ74BL) and MOSFETs at:

Super service from Jack. Highly recommended.

I also received a nice package from the US (Jack)...now I have JFETs for a few Pass projects

I heard Jack was a Quack who's gone to the dogs.
But maybe i'm mistaken with a different operation and another Nelson alltogether.

(I suppose a pair of pyjama boards with Dr Bob printing is out of the question ?)

As a kind of dedication ? ... Sure, would be fine

Board+chassis(kit) also possible?
Your response thanks...

At Dubai airport...

 

[Babowana]

I means the chassis that incl. your nice heatsinks...

 

[chrismercurio]

Maybe if you come to burning amp this year he will have more heatsinks for gifting....but maybe it was a one time only event as the word has spread.

I have never been America yet even though I know who Bush is.
And, I feel the "burning amp" is too far from me.
I'm just asking. Even if the answer is no, I'd loose nothing.
But, who knows?

Waiting four hours alone for the boarding is one of terrible things...
I have to drink which I do not want.
I should do smoking that I should avoid...
I hate my job...

I have liked F5 and I like Papa's heatsink design very much...

Regards to everybody...

...know where I'm getting mine!!! YEAH BABY!

ps...you better make some extras for this project!

 

[Manu]

Slight Dubai airport depression babo?

 

[Babowana]

Yeah...

I'm trying to keep positive way of thinking as much as possible.
Nevertheless, four hours waiying is a torture...

One hour left...
Tomorrow I could sleep with a beauty...

 

[Manu]

Tomorrow I could sleep with a beauty...

Hehe. Thats positive enough ...
What can life offers that is better?
Be well

....this caveman gives it a try....

A bit hesitant to post, since this is my first attempt at ever making a pcb, but I have come up with the following layout. The board is 6 inches by 2.5 inches,as I wanted to be able to get 2 boards out of a 6 by 6 blank. Please let me know if there are any major problems or if I should just scrap this one and wait.

Thank you Mr. Pass for providing the impetus to try this.

Steve.

edit.....resizing

edit #2, try as a pdf

 

[spind]

And, since I was on a role, here is another try, with *jackinnj*s modifications.....

I forgot to show the board outlines, but they can be imagined...

I think I know what route I'm going now. That'll give me time to save up for a better chassis and some flashy heatsinks. As always, Nelson, you're the man!

[jacco vermeulen]

There's only 1 route : parallel and bridged, 250W of dissipation for 100 watts of pure Class A in 8 ohm, with enough output current to swing your big mammas.

 

[Nelson Pass]

That's quite practical.
