Building a Nonlinearcircuits PSU.
This just supplies +/- 12V for Eurorack modulars.

In the NLC build notes, Andrew stresses the importance of isolating the regulators from the heat sinks.

The smaller heatsinks came with grommets and mica insulators, so I think I'll use those.
He also recommended using heatsink paste.

Ok, lets twerk
The PCB receives 12VAC from a plugpack/ wallwart
. The 1N4004 diodes split this into positive and negative waveforms.
The 4700uF capacitors then smooth out these waves
. The 7812 and 7912 regulators then convert the rectified & smoothed
signals to +12V DC and -12V DC and these are fed to the connectors to be distributed to your lovely modules.
I'm using 250v TDK film caps for the four small 100nf caps
Probably a bit overkill, but it's what i had in stock at the time.
Some pics of the 7812 & L7912 voltage regulators attached to various heatsinks.
