Well Suds seems to be quite a nice quy,after I mentioned the cut in the PCB, he wrote me he will send me a new one. Even thou he says It must have happened during the transport.
So I will keep you up to date on that.

OK I have got my Camera back 🙂
here are the pics of the PCB and parts fot the amp, I only miss now the part for the power supply.

As you can see on the first picture there is a cut on the PCB power supply - I hope it will be working with the cut as Suds dont send me yeat a replacement...

You, lucky man, Daniel! Your girlfriend really loves you!
I can't see any serious cut on your PSU PCB... 😉
BTW, what do you think about to have 230 V on this PCB?
OK, it's original solution from Mr. Pass, there's no doubt...
Finally, what's your next step? (the same question for generg too)
& for fun!The cut is in the R8 resistor of the power supply board.
Next steps are, get the money for the casing, a 5U rack seems to be the solution. As long as I dont have the case I hesitate to start the building as I dont want to have a assebled PCB lying around, with the sensitive parts. I hope to have the money in mid december.
Then as well I still dont know the parts for the power supply and I need to solve the 230V issue.
YOu know Im quite a noob on that so I can assembly the PCB but need someone who would give me the parts list and advice, as well I still dont know what transformer I should buy.
How about you?

I took a look at the F3 pcb photo here. I'm a little confused as to why the mounting bolt holes and silhouettes for the power devices are there. How do you plan on mounting the power devices to the heatsink?
Daniel, don't need to worry about.
You say you are new on the diy audio floor... If so, it's even better first to build on the bread board. Believe me... (i'm new too...)
As said before, have to answer the question about PSU PCB (original or some other). I am inclined to the second (with all respect to Mr. Pass solution!)
Add., original PSU solution allows only caps with up to 30 mm diam. 😕
About transformers...
My plan is dual mono (250-300W each, with sec. 2x18V, or 1x36V).
& for fun!Does it mean, you will not use the original board for the power supply?
Dual mono, I thougt it is a dual mono amp...?
I will build it as it is, one power pcb and 2 mono pcbs.
Still I have no idea abou the capacity of the caps and where what to conect on the power supply...

Well I will need a L profile to mount to the pcb and the profile to the headsink
OK looking at the scheatics ...
the caps should be:
15000UF 25V
Resistors:
48OHM 3W
and the termistor typ CL 60
any further recommendations?

The PS schematic in the service manual is a dual rail PS, and the F3 uses a single + rail. The first set of PS caps should be at least 63V.
Wel thank for the nonconstructive feedback, but its writen at the second page of the service manual is 47 Ohm, only the R9+R10 are 2,2K
Hi Daniel,
do you speak about PSU resistors (R1-R4, R5-R8) or something else? 😉
& for fun!I assume we have the same F3 amp manual. If so, than also the resistance for mentioned PSU resistors have to be the same: .47 ohm (0.47 ohm).
Am I wrong?
& for fun!- Status
