You guys are building some nice amps, I think I found my next diy project. This is a lot of information for a first time amp builder to take in, thanks for helping to simplify it (somewhat). I need to hook up with Cviller for boards first if still available. For stereo I need 2 F5 boards 1 Psu board and 2 bridge boards, is that correct? One more question, is it better to order parts kits from Tech-diy or should I order individual from the Pom for best compatability with the pcb boards? Thanks for the work you guys put ino this.

Correct, on top of speaker outs/RCA inputs switch, fuse, IEC, etc.
Ordering from Tech-diy will be the easiest solution, and 10 or so pages back mentions that jack from techdiy worked with cviller to ensure proper fit/compatibility
Thanks for the response ...dusta, currently reading over the PassF5 thread. That is a huge thread

You are a brave man!
We'll see when it comes time to flip the switch for the first timeYou are a brave man!
Do you still have all the boards available? If so, I will be making an order from you in the next week. I'm currently still gathering information and purchase lists, I certainly want to join in on the F5 fun. Any idea about how many sets of boards you have sold so far?Tony

Glad to see this thread still kicking!!
My F5 is working great but I have a slight hum in both speakers that I would like to get rid of.
The speakers are very efficient at about 95db and with no music playing I can hear a hum from about 3 ft.
I was wondering if anyone is using a "star ground" and if so how is it connected??
I would like to try this to see if it will help.

rtate, could you please take a picture where we can see the wiring or draw a (detailed) diagram of your wiring? Someone might be able to help you then. My F5's are very quiet, but I have a chip amp that picks up mexican radio!!!
Mine is wired like this:

Thanks Christian, I have wired my F5 as per your picture above.
At this point I do not have anything connected to a "chassis ground"
only the safety ground is connected which I have tried both on and off.
I have been moving my gear around latley and will take some photos as soon as I can....

I have not read this article, but it may offer you some advice/clues while we are waiting for the pictures:

Rtate,
If you unplug the RCA interconnects from the F5, is there still a hum?
If not then it is caused by an upstream piece of equipment or cable.
Next try, Unplug the other end of the interconnects, CD / preamp / receiver, whatever, leave the interconnects on the F5 side, try them one at at a time, left then right. Sometimes it can be a bad cable.
Sometimes the interconnects act as antenna. But you knew that.
Try unplugging everything from the power except the F5. Hum still? Is the transformer bolted down tightly?
Keep us informed, especially if you DO find the hum source, it will help someone else.

Thanks Guys, I did some investigation when I got home from work and once again Never Assume!!!
Turns out that the F5 IS dead silent.
I have a plate amp that is driving the low frequency drivers and that is the source of the hum.
So I still have a problem, just not the F5.
Now, for some more investigating....
