Could you point me to the F5 article?

Thank you very much.

Note that there are still two pairs of Conrad heat sinks left on ebay.

You can find it on www.firstwatt.com

can you be a little more specific?

You'll end up with the pdf on the third mouse click if you go through "articles" and on the fourth going through the "products".

Seriously, this site should be one of your favorite references when building pass amps.

Thanks Jim. Even though I've been navigating the www since Al Gore was poopin' yellow, I couldn't find that article. Why it isn't in DIY is beyond me.

Now it makes a lot more sense! Sorry for being cranky, I thought you were just lazy.

You should also read my guide ( you can find it on the F5 PCB WIKI )

I have just sent out some more boards.

Now I only have 12 PSU boards left, but I still have plenty of F5 boards.

It's in the article somewhere (http://www.firstwatt.com/downloads/F5-om_sm-080527.pdf) - I think it is should be rated for 30A or 25A and 250V. You can get them anywhere and they are called a diode bridge. Do a search on "diode bridge" on mouser and click rectifier something a couple of times and you'll end up with a couple of thousands to select from.
I can't really recommend any, just make sure you get one with the correct or above rating.

I have used these,
Mouser

844-GBPC3506A
844-GBPC3512A

Mainly because they don't cost too much

Dont forget BER142 Heatpads for these things.

You use a heatpad on a bridge? Is there an advantage over
just using silicone paste? I'm not arguing I don't know just curious

I thought they needed to be isolated from chassis. Maybe not.

I't probably doesn't matter much. They don't put out as much heat as output transistors.

They are isolated internally from the package

Usually not. Single or dual diodes in to-220 or to-247 packages do however need isolation.

 

[toufu]

Hi, do you still have boards left? I need a pair (for stereo). Thanks!

Hi cviller and F5 bunch,
Looking forward to joining in, just an intro.

Cviller, you have PayPal payment and email(s); Hope I didn't confuse by forgetting to include my DIY user name with paypal on the 18th.
Charles

 

[cviller]

That's no problem - I could easily correlate your name to the payment.

toufu, just send me an email if you want to buy some boards. You can find all the needed information on the WIKI.

By the way I have 5 psu and 40 F5 boards left.
