Doesn't have to be, but it is good idea to place them very close to each other. Just make sure you don't get unwanted electrical connection.
Hi Christian,
as i mailed you personaly i have received the boards in good shape, they look great!
However i do not have experience with amp-building.
I have searched , but couldn't find much info on the rectifier-boards...?
Could you please post a picture with parts onto it and how it is connected to the rest of the PS ?
I may be a newby, but a clean start is better then a lot of smoke
Thanks,
Al

It is kinda difficult to take a proper picture of the boards with components due to the heatsinks, but I have attached one.
For external connections, you could take a look on this one:

(it is with block bridges, but the principle is the same)
Here is a guide I have written, which explains a few things:

And of course you need to read the article by Nelson Pass:

I'll try to dig up the schematics for the bridge.

CViller,
That is one COOL looking bridge rectifier!
Very nice design job. Thanks for the links on building.
Thank you for making it easy for us Noobs to build the F5 as designed by Papa. The Master.
I'm waiting on funds to buy a set of boards from you. They are Sweet!

I will be quite unreliable the next few weeks - I have some wedding stuff which needs I need to attend to... 😀
And then we go on a few weeks of vacation, where I won't be able to log on. Guess it would be quite unpopular if I did!! 😉
You can still order when I'm away, but expect a few weeks of delay. At the moment I have sent all ordered boards and still have some left. I'll most likely close my order site when I run out of boards.
Hurry.....GO!
CViller,
Payment sent just now.
If you don't ship before you go on vacation, that's OK. I just wanted to make sure I get a set of boards from you before your sold out.
Thanks,
Ron

Re: initial rail reading
Alazira,
could you point me to that PS pictoral by Udailey please, Link would be even better. I don't think I'll need it but it wouldn't hurt to look at it either.
Thanks,
Ron

Hi,
This was my 1st amp build (thanks N. Pass, C. Viller for boards, and U.Dailey for step-by-step power supply pictorial)
I got 2SK170 and 2SJ74 for Q1 and Q2. But the foot print is different than the board according to the datasheet.
Am I suppose to flip them around?

Dont rely too much on me 😀 though I think you look at datasheet the wrong way
First picture is seen from front, the flat side, and seems to be in line with boards
What may confuse you is the second picture which is seen from the bottom, not from the top, as you seem to look at it
But remember to read Cvillers manual carefully, about changes and silk screen fault regarding BC###
Back from vacation!
I have sent the four orders I got and you should have received an email by now. So there are no paid boards unsent. 😀 (please email me if I'm wrong)
I will have to close my order site down, which I will do Thursday night on the 2rd of July. I still have plenty of boards, so feel free to order and I'll send them in the weekend.
I'm moving to San Francisco on the 13th of July, so I will not be able to ship boards while I'm moving.

Hi Cviller
I have downloaded your F5 file, so we should be able to share it among us
Ehhh, maybe we will get greetings from US
San Francisco sounds exiting
Good luck

Cviller,
Welcome to California.
The first state in the USA to be Bankrupt due to our politicians being overly generous with our money!
It will be a pleasure to welcome you to "Burning Amp" this year. I hope you enjoy living in the "states". Thank you for making/mailing the boards.....I can't wait to stuff them.
See you soon!
I live in Sacramento.
Ron
Where and when will be the BAF 2009 held?
It would be a treat to see the gurus there...
Welcome to the states Christian!
