While waiting for some comments, I made a test layout of the Rectifier/Cap board without onboard CRC, but with possibillity for external CRC circuits.

Lenght then redused to 29.5 mm

Hi Jan

I also have no problem with this longer board. My only comment would be that you could probably fit in three off 3watt CRC resistors in the space you have shown for each rail on the PCB.

If people do not want to use the resistors, they can simply link them out, or wire in an external off board inductor for those using CLC filter.

Regards

Gary..

Gary;

Yes! There is room for three 3W resistors if CRC connectors are removed....

However then no room for proper connection to external circuits.

Hi Jan.

Perhaps you can have pads for the CRC resistors on the board and then another 2 pads to connect an external inductor. Forget about connectors here. Just my thoughts.

Regards

Gary..

Hi Jan

This looks good to me. You have all bases covered from what you have shown here. Now all you need to do is add some nice heavy tracks for a stiff low impedance power supply that will suit all class A and A/B amp designs from 10 watts to 500 watts per channel

Good work, and I am sure you should get good interest for this design.

Best Regards

Gary..
