Hello everyone.
Following the realization of several people of a class A amplifier (USSA-5 of Fab), I decided to draw a PCB dedicated especially to this one but that can be suitable for any other amplifier.
I wanted to do something fairly universal and practical and I told myself that this PCB might interest more people.
Features:
Size: 160mm x 100mm.
Possibility to put four capacitors up to diameter 40mm.
Possibility to put diodes (to220) soft or high recovery (capacitors provided).
Capacitors in parallel on the inputs of the diode bridges.
Possibility of putting an 'RC snubber' on the inputs of the diode bridges.
Possible resistances between capacitors from 5W to 10W.
'Bleeder' resistors from 3W to 5W
The latest version brings the possibility to put 5-legged capacitors and TO247 box diodes.

An externally hosted image should be here but it was not working when we last tested it.

For the price, everything will depend on the number of people interested.
Ex, for a 2oz production of:
10 PCB => $ 4.5 each
15 PCB => 3.6 $ each
20 PCB => $ 3.5 each
25 PCB => 3 $ each
30 PCB => $ 2 each
Etc ...
Add the shipping costs.
Currently there is a demand for eight PCBs.
I will have the actual price at the end of the purchase group according to the number of people and confirmation will be made at this time.

OK!
You can follow the other buying group on Quebec Diy.
USSA - CRC Power Supply
Currently we are 14 to 18 board.
I keep you informed of the progress and I hope that others will join you in bringing down the cost price.
Thank you.

Hello,
what tickness is the board? Color? I would prefer 2oz, 2mm+ tickness, black, blue or red.White solder mask. Alternativ c-c-r-c-c with no diode section.

Put me down for 6 x
Only request is 2mm+ thickness as per gwrskien and 2oz. Indifferent regarding color.

Hello everyone
Currently with the demands on Quebec Diy the cost price of each PCB is 4.25 $ (US).
I hope that other interested people will come because this will decrease the price again.
I confirm that the PCBs will be in 2oz and 2.00 thickness.
For color, we will vote at the end of the purchase group (I have not yet chosen a date).
In some time I will put the list of buyers, I expect just one or two confirmations for the requested quantities on the other forum.
Thank you all! 🙂
Edit:
The price above does not take into account the demand for gwrskien, so it must be lower still.
I will therefore from now on indicate to each request the price of the PCB.

I think to start manufacturing in early next week as soon as 75 PCBs are requested, if there is a little more the maximum will be 100 PCB.
Here is the updated list.
Fab (2 boards)
Pinnocchio (4 boards)
Nounouchet (4 boards)
Haddock (2 or 4 boards)
Mcandmar (4 boards)
Project16 (2 boards)
AV Freak (4 boards)
Steve1 (4 boards)
Muhy3 (6 boards)
Myint67 (8 boards)
Gwrskien (10 boards)
Asuslover (2 boards)
Ssarchy08 (4 boards)
Morde (2 boards)
Ryssen (4 boards)
I have not checked yet but we should be around 4$ (US) each PCB (+ shipments)
I will tell you just before starting the manufacture.
Thank you.
