Gb: F5 Pcb

[acold7dusta]

Yes, thats correct. In general I have just added 100 to the stock F5 parts for the optional stuff and the cascode numbers are just different... makes sense? Probably not, but I'll see if I can wrap up a guide tonight with a better explanation.

Great, easy enough to follow

Thanks

Christian,

Got my boards safely, thanks! Next time I'm in SF, I'll look you up. I have family there. Looking forward to the updated guide.

Best,
Anand.

PS, received the boards yesterday! As it's been said multiple times, great quality! Well worth the wait.

Great to hear the boards are landing safely! 😉

I have started a blog post where I will make the guide to the boards. It is not completed, but I decided to publish it so that you'll have access to the BOM and schematics.

I'm really pleased with the looks of this batch of boards the blue and gold goes better together than I had imagined. 😀

Here is a shot of the F5 v2:


And one of the F4:

Perhaps there's some Swedish in you?

Ha, ha, ha!
No Tosh, you're wrong!
Christian sings from day to day: "Blue sky, blue sea, blue me!" 😀
BTW: we all know why "blue me" 😀
Cheers,

- no not that I know of at least! 🙄

 

[cviller]

I had expected to get a lot of "noise" after posting the bom, but perhaps everyone just orders from techdiy.

Very nice boards arrived safely - many thanks for your efforts 😀

Just love the finishing on the corners btw

Smokey LIVES! one channel anyway.....

Hey Christian,
Do you have any of the older style (smaller) boards left? Yeah, I need another one. Too many times removing parts from one board to another I guess.......... While bias them up today I got a smoker. Surprise. I just love that smell. One channel is running just fine, but I'd prefer a stereo amp to a mono.
I'm going to order NEW parts this time and not try to save and reuse the old ones. I'll get my F5 Yet!

Thanks,
Ron

I should add that I only need ONE board, not a pair

Hello Christian,
I received the PCBs this morning and also today I have finished my F5 built with your F5 PCBs from a year ago.
The new boards are very nice, it's easier to spread the transistors on the heatsink.
Here's a picture of my F5 with your PCBs v1. I used an alu U-profile to put the transistors on the heatsink.
Thanks!
Danny

Boards arrived today - look to be top shelf first class.

We'll know for sure when the parts get shoved in, and we solder on the pads... 😀

Hello Cvilller!
I would like to have a pair of F5 boards. I am new to this so if you could give instructions how to pay and give you the delivery address.
best regards

Hacksawed Cviller Board

This weekend I finished putting together Cvillers boards.
Since they did not fit into my cramped quarters too easily, I hacksawed the ends off. It's outfitted with the caddock power resistors which fit perfectly.
The heatsinks are overkill, but allows them to dissipate some heat for sure.

Didn't see this until now, but I can see you have found my order page. Your boards are on their way. 😉
If others are interested, you can have a look at my blog for instructions - I still have plenty available.

Looks interesting, does it play yet?

 

[Tea-Bag]

Sure does, two channels even. I think Caddocks help add a smoothness and clear sparkly top end with the PRP's, all else being equal.

Of course my outputs are Toshiba's biased at 750mv.
