Hi,

Farnell has these as well - just search under their "ECM40US07" name.
Btw. I would recommend to replace them with the ECM60 variant (60 W instead
of 40) which has a bit larger components and may heat up a bit less under
load.

Another recommendation would be to not reinstall the aluminium lid of the power
supply enclosure to províde a bit better air supply to the poor power
supplies which are otherwise getting barely any cooling (hence the top 7 V
supply is being grilled by the two lower ones)…

Best regards
Bert
