+1
And maybe a 3-pin footprint to be truly universal.

I ordered a few of these for testing from Mouser.

not the best reating 2000hr@85deg but in a well ventilated solid state amp should last a while.

I am really confused - can anybody tell me if this $29 PCB kit has a total space for 8x capacitors or it's 2 double boards for a total of 16x capacitor?
If it has to be $55 for just PSU PCB for my Turbo v2 build then it's a bit expensive...

Thanks!

What you see is what you get. There are two rectifier boards and two filter cap boards - one for each rail. Note the scoring lines where you can break apart the supplies for each rail and/or the rectifier boards to fit your case layout.

If you want to go dual mono for your F5 you will need two sets ($58).

thanks a lot! So 8 cap space by default. I am going stereo v2 so with my 10000uF caps it is recommended to go 2x8. Now some pics were showing these installed in the big amp case showing 2x8 caps so I got confused. I guess I need capacitor boards from 2x kits just not sure if I have to get these with extra 2x rectifier boards...

If you order 2 board sets you will have 4 rectifier boards and 4 capacitor boards. You don't have to use a bridge rectifier per rail, but there are a lot of folks who think it's a good idea.

You can always offer up unused rectifier boards in the swap meet or use them on another project.

What is the advantage of dual diodes as opposed to single such as Fairchild FFPF30UP20S? Can only dual be used with the board?

^^ The pin out is the issue with the Fairchild part.

Actually I see in the build thread that TO-220 can be used with a bit of manipulation of the leads. Do the dual diodes offer a big advantage to a power supply?

Other than current rating, the actual type of diode can be important. Standard, fast recovery, soft recovery...
