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)... ;)

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!

:cheers:

So the PCB´s arrived today a nice piece of work, unfortunately it one has a scratch on in, but its in a midle of a arrea of a resistor so I hope it dont makes a difference, its on the power supply part.
I would appreciate a diagram and parts list send as well, but only the boards arraived. Newer the less it took just a week to get them and they are pretty nice.

Good news! I'm happy too - with you... ;)
As I have already explained you have all what you need to build F3 amp on F3thraed & on NP FirstWatt site (see link above).

Thanks, ...

you know Im quite a noob, and well I looked the F3 builders thread up and down but I still will need more guidance :(
For example I have no idea what type and what performance of the transformet I should buy, im missing a part list for the European 230V fot the power supply.
And so on. Thats as well why I made this thread.

PS:Suds, thanks for the PCB´s
