Rebuild kit for Williams Defender Linear power supply.
(Revised, now includes BR1, BR2 & BR3)

This kit contains the components to replace the ones most prone to failure,
it does not contain every single component on the pcb, just the ones renowned for failing.

All components are brand new.
Please note when fitting that some components are polarised and therefore
need to be installed the correct way round or damage may occur.
