Similar to this. 1mm thick works well. You can get from Amazon for more and faster.

No, I can't. The power devices are soldered into the board and have rubber caps, but the holes for the mounting clips are above the devices, so no chance without clips. I also have to solder the thermal switch, but it's not a problem.
I hope he will send me the clips... Or I have to drill new holes and use Keratherm insulation between the devices and the heatsink... but it's not what I paid for...

Mikebarney did a fantastic job on this amp. Congrats! He made a nice write up of his build here:

Hi X,
could you please check and correct (if needed) the following wiring plan for the psu?
Really not that much![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Many thanks in advance![cheers :cheers: :cheers:](https://files.diyaudio.com/forums/images/smilies/cheers.gif)
could you please check and correct (if needed) the following wiring plan for the psu?
- Main voltage output with the big connectors: to the amp board, it's clear
- 12 vdc output to the buffer
- 3.3 vdc output can be used for an LED on the front with a resistor in series
- AUX (15 vdc) to the amp board - but in your build (and in the picture above) I see a cap on the top of the connector; is it against turn on bump? If so, which value/voltage is needed?
- How/where to wire the further contacts (STDBY, DCER, DELAY?)
- PSU input is J1, whit the left contact live and the right contact neutral? Middle contact not in use?
- J2 has in your build (and in the above too) a jumper - what is it for?
- Where can I set the input voltage to 240vac?
- mains fuse value at 230vac?
- Is the turn on button a locking one or just a push button without locking?
Really not that much
Many thanks in advance

Vunce,Plott,
Did Sami give an explanation why the SMPS wasn’t 100% assembled?
mainly because of the time; they have long delivery time now as stated on the homepage (at the time of my order it was at least 35 days) and I wanted it a little quicker.
And after the psu was on sale, I accepted the assembly, which was really not a big issue.
