Default CRC Power Supply (Class A amplifier)

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.

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.

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.
