How to build the F5

Woody - Yeah, it's taking lots of twists and turns, but there is not that much that can be done about it now. There is still lots of good info here, much has been shared, and lots has been learned. Enjoy the ride. Once I am done I will make a new thread and in a flurry of posting get it all documented so it's hopefully on one page. (That will load really slowly due to the images!) 🙂


CanAm Man - Yes, the transformer primaries have been tested and they are mated correctly. A good thing to ask, regardless. As fun as a good fire would be, I think all it would do is blow the fuse...

Everybody else - Hopefully I get a chance tomorrow to do a final assembly on the amp modules, and piece this beast together. I would very much like to (at least) have the chassis screwed together and ready for the final wiring.
 
I am sorry to have to disagree with Woody

From what we have been trough quite a lot is been discused about the stock build.
The use of Artic silver for one thermistor another good point I think.

Chassis yes not stock but IMO quite a bit of what can be done Ist have another look at the pictures posted by Peter Daniels I think there is a lot to learn there.

Capacitors on the Bridge and filter

So far we have not even started with the F5 propper.

Let me ask you a question

WTF (exactley the way you put it )did you and CO. post that can be of any walue?
 
Hi jacco
Out of topic

I was thinking about fitting the Sinks fins to fin and then (like in the Dennon posted by Peter) bolt the fans under the sinks as I got 300 X 83 a aouple of 160 fans suck air troug chassy and posh it upward troug the sinks ciminy efect should help what you think?

Out of topic 2

Jacco have you seen a Venetian gondola in Rotterdam?

That's a good way to look at it, I figure if I start a build thread before I'm done and present it as I build, it is natural for a lot of off topic banter to occurr, and its usually entertaining as well as informative.

If on the other hand you want a thread to begin with what you have to present and end that way without interruption, either have a separate build and discussion thread, or finish the project like you said, and then take all your pics, and post the thing in one session. Then comments will follow.

Your threads have been some of my favs lately, so thanks for the posts.

Hey guys. I have my f5 boards ready, heatsinks on the way.

I know this has been covered but I'm buggered if I can find a simple answer.

What parts do I need for the Cviller CRC PSU? A generic answer is fine, the plan is to use a 18-0-18 Toroidal.

Cheers for the help guys.

You'll need 8 x 15,000uf/ capacitors, 8 x .47 ohm 3 watt resistors and two 2.2K ohm 3 watt resistors. You'll also need two fullwave bridge rectfiers that are not on the PS board.
 
Umm, can you use a 18-0-18 transformer???

I thought you must have a 0-18,0-18 so that you can have 2 rectifier blocks...

Can you have two bridge rectifiers on a center-tapped transformer? I honestly don't know, hopefully somebody can chime in with a good answer...

I found these:
400V 25A Bridge Rectifier

For the full wave rectifier. What do you think? Is it worth spending more for say "Vishay" units or does it make no difference?

The specified part is a 35amp rating, I don't know how critical it really is. Anyway, the Vishay parts are 16 cents cheaper... 🙂
