Universal PSU, Capacitor and Diode Combination Board (V2)

[JojoD818]

I pre ordered several Universal Power Supply Boards and am trying to collect and order my parts. I was planning on using TO247 diodes with heatsinks. The board has an outline of a heastsink. Is there a part number or designation for a heatsink that fits the board.

Thanks.

Please also check the BOM, the heatsink part numbers are there.

Thanks

So, this board *cannot* be used with a center tapped transformer?

Why not?

It seems one poster is running out to buy new transformers.

So, I'll rephrase it as a question:

Can the Univ. PS. be used with a CT transformer?

How does that get wired?

I probably can't be used with a center tapped transformer and dual bridge rectifiers for a First Watt amp. But it can for used for other purposes. Depends on the project. Also I don't believe dual bridge is absolutely necessary, but reduces transformer hum. If you are planning an F5 or other First Watt project it's best to use have dual secondaries.

Yes it can. Compare also my SPS01 we had here as a group buy some years ago.

I have been unable to measure any difference in PSU performance between a dual secondary dual rectifier arrangement and a centre tapped single rectifier arrangement, other than the extra 1.4V lost due to the extra diodes in the dual rectifier.
