Building F3 - Clone Suds version

[imagios]

Hi there,
I order recenlty the PCB´s from Suds. As I saw there are F3 building threads, but based on Peter Daniel´s version of the PCB´s. And as more of you got the PCB´s from Suds as well I thought it might be a good idea to star one just for this version of the clone.

Until the PCB´s arriwe I would like to order the pars as well. But cant find a parts list. As Im not very experienced in electrotechnics I would need some advice on the power of the transformer and some of the parts.

Has anyone finished this clone of the F3 yet?

Cheers,
Daniel

PS: Note to admin can you please move the thread to the folder of http://www.diyaudio.com/forums/solid-state/ I had two windows open and mismatched them, thanks

Hi Daniel,
seems to be good idea to open this thread - thank you!

Otherwise, you forgett everything...
Please, belive me jackinnj (Tech DIY Company Store) is your friend for both - F3 BOM & parts

Do you beliwe they can as well send the items "paired"
What transformer do you recommend 300VA 2x18V?

Hi Daniel,
not only that he (jackinnj) can, he will (see photo below)...

Second photo: suds PCBs & heatsinks 40x165x400mm (from other supplier)

Nice I ordered my parts as well today )

To the headsinks: 40x165x400mm do you belive that will be egnouth? for such amount of head?

Well, let's see...

Since F3 PCB is unusually long (300 mm) it's not easy to find appropriate HS.

My start point was info from Mr. Pass in original F3 thraed that minimum thermal resistance (TR) should be 0,25 Cel/W.

HS calculation (see below) confirmed above.

In catalogue of my HS supplier I've found that his HR-400 HS with 150 mm length has exactly needed TR (see below).
To be without any doubt on the safe side I've added 10% on length (from 150 to 165 mm).
In original F3 thraed you can see different solutions. Some are very close to that criteria, some HS are significantly bigger. OK, i know & respect the statement (think it's from Mr. Pass) that there's no to big HS...

On below photos you can compare data of my HS with Conrad MF35-151.5 (used from member ZUM911). Not very different... Also interesting is to see and compare the original Nelson Pass FirstWatt F3 HS (see below). It's about 63,5x127x356 mm but with less efficient air flow.

My "gold reserve" is alu housing (i prefere skeleton building).

Any comment or advise is appreciated!

Well I think there is nothing to add. Im quite a noob, to add something to your qute clear calculation.

Btw: how much time took it before you go the PCB´s ?

[imagios]

PS: can you as well share the link to the shop with the headsinks, im still not sure what to choose...but this might be definately a possible choice.

[imagios]

I can only hope to get my PCB´s it looks the seller is not much reliable:
Reissue: F3 and F5 PCB's Group Buy

About two month.
